If, by log x², you mean log₁₀x², then:  log₁₀x²  =  4   --->   x²  =  10⁴   --->   x²  =  10,000

--->   x  =  √(10,000)  =  100 

You can use the ( ^ ) key.

Set the expression to y:  y  =  (-3x + 4) / (x - 1)

There are two steps:

Step #1:  interchange the x and y terms   --->   x  =  (-3y + 4) / (y -1)

Step #2:  solve for y:     x(y - 1)  =  -3y + 4

                                    xy - x    =  -3y + 4

                                    xy + 3y  =  x + 4

                                   y(x + 3)  =  x + 4

                                            y  =  (x + 4) / (x + 3)               <---  This is the inverse ...

27^2/3

The numerator of 2 means to square the number. The denominator of 3 means to find the cube root of the number. These can be done in either order.

27^2/3 =  (27²)^1/3  =  729^1/3  =  9

27^2/3 =  (27^1/3)²  =  3² =  9

Multiply any three prime numbers together to get a composite number:

For instance:  3 x 5 x 7 = 105

Can you find two more numbers?

The first location (on the left) will hold one of the 7 math books.

The last location (on the far right) will hold one of the remaining 6 math books.

The middle location (location 6) will hold one of the four history books.

There are 8 books remaining.

In location #2 (from the left), place one of the 8 remaining books.

In location #3, place one of the 7 remaining books.

In location #4, place one of the 6 remaining books.

In location #5, place one of the 5 remaining books.

Location #6 is filled with the previously chosen history book.

In location #7, place one of the 4 remaining books.

In location #8, place one of the 3 remaining books.

In location #9, place one of the 2 remaining books.

In location #10, place the last book.

To find the total number of possibilities, multiply these numbers together:

      7 x  8 x 7 x 6 x 5 x 4 x 4 x 3 x 2 x 1 x 6 

While the previous comment was highly sexist, seeing as many girls are excellent at math, I think it had the right idea. You shouldn't be looking for a mate on here; this is a math website. Not an online dating site.

$$\mathbf{3^{-2},5^{0},2^{-3},-7}$$

$$3^{-2}=1/3^{2}=1/9=\mathbf{0.1111} (4 d.c.p.)$$

$$5^{0}=\mathbf{1}$$ (anything ^0 = 1. See how: $$2/2=1$$     $$2^{6}/2^{4}=2^{6-4}=2^{2}$$    $$2^{6}/2^{6}=1=2^{6-6}=2^{0}$$)

$$2^{-3}=1/2^{3}=1/8=\mathbf{0.125}$$

I think you will be able to order them now :)

They are right. You should ask for a boyfriend instead of a girlfriend. There are many more boys than girls on here. Girls can’t do math --it’s too hard. Even if you find one that can do math, all that means is she is smart enough to find a boy to take care of her –that is actually pretty smart. Smarter than most boys who can do some maths.

slope  =  m  =  [ y₂ - y₁ ] / [ x₂ - x₁ ]

(x₁, y₁) = (-4, 7)     and     (x₂, y₂) = (-6, -4)

Substitute:  m  =  [ -4 - 7 ] / [ -6 - -4 ]  =  -11/-2  =  11/2

I may be gluten free, but I will not be your's, seeing as bring gluten free is not a qualification for ownership.

To find the number of packages, divide 84 by 12 ...

When the exponent is  -1/4, the negative sign flips the problem into the denominator

(16x⁸)^-1/4  =  1 / [ (16x⁸)^1/4 ]

The exponent of 1/4 means to take the fourth root:

16^1/4  =  2  and  (x⁸)^1/4  =  x²

=  1 / ( 2x² )

It is totally 21!!!!!!!!!!!!!!!!!!! 

Hi Julliette, I am Kate:):) they can see more colors than black and white, I am reading the book flipped give any hints of who I am? 

Good news!  

I went to my user control panel and it let me change my password, and without requiring that I type in my old one!  

My browser remembers my password, but I don't know of any way to make it tell me. So I've set a new one, and all is good now!  

Thanks for the hints people sent me.   

Who wants to be your gluten free?????? G means many things. Also, don't ask this on a math website

What an annoying highlighter color.
1120 divided by 8 is 140, so 140.

log*x^2 = 4

taking inverse of the log function of both sides,

x^2 = e^4

taking square root of both sides,

x = ±e^2  (Answer)

Pi isn't an equation. It's an irrational number, very big difference.
There's no last digit because pi, as an irrational number, will never terminate or repeat since it cannot be expressed in a fraction form.

Basically, you just want to divide 1,120 by 8.

1,120/8=140. 

This is just a one step problem :)

Hi, sorry for the late response. 

First, write it out. Helps see it better.

6 1/2*65. 

Make the mixed number into and improper fraction so you can multiply.

13/2*65

13*65=845

Finally, divide this by two. 

You will get 422 1/2.

Mean: 8+8+9+9+7+9+6=56 Then, you divide by the number of numbers. 56/7=8 

Median: First, put them in order from least to greatest. 6,7,8,8,8,9,9. Find the middle of all of them. It would be 8. 

Range: 9-6=3. 

M.A.D (Mean Absolute Deviation):

You use the mean and find the difference between the mean and the numbers you were given. After that, get the absolute value of them. |x-#|

So, 8-6,   8-7,    8-8,    8-8,    8-8,      8-9,     8-9

       2.       1.       0.       0.       0.        1(a.v)   1.(a.v)

Finally, find the mean of the differences. 2+1+0+0+0+1+1=5. 5/8. (0.682)

the resultant of the two vectors as an ordered pair <3, 6> <5,-5>

We also need to know whether these are to be added, subtracted, or multiplied. I'll assume you want these added. In that case, add the corresponding numbers....

= <3+5, 6+-5>

= <8, 1> (Answer)
