Yes, what do you mean?

What do you mean? Like 2*2*2 --> 2^3?

A great answer Ninja 

You would just use - (^-3, for example).

On the on-site calculator, make sure it is set to degrees mode on the bottom and do atan(0.83).

757 - 596 = ?

?*596 X 100 = % 

Sorry, I was sleepy...I...Fixed...It...

DS, 1/4 is 0.25.

Get common denominators:

-5/1 --> #/4...to get #, you need to multiply -5 by 4.

Then, simply subtract. Note that your answer will be negative.

Cancel. Nice, CPhill.

Let 22-x be the length reserved for the square and let (x) be the length reserved for the triangle.

So (22-x)/4 is be length of the side of the square and (x/3) is the length of the side of the equilateral triangle.

So the area of the square is given by  [(22-x)/4]^2 = (1/16)[22-x]^2. And the area of the triangle is given by

(1/2)(x/3)^2sin(60) = (1/2)(1/9)x^2(√3/2) = (√3/36)x^2

So the total area is given by

A = (1/16)[22-x]^2 + (√3/36)x^2

$$\frac{1}{4}=0.25$$

Thank you! It was kind of hard

WEB REFERENCES:

Differential Equations;

Subtract 9 from both sides.

Divide by -6 to obtain x.

Every even number can be written in the form  2n....Therefore..

2n * 2n  = 4n^2

But 4n^2   =  2(2n^2) and this is divisible by 2 for any integer n ....and divsibility by 2 is the definition of an even number......so an even times an even is always even.

I assume this is log₅ (3x-7) = 3

5^3 = 3x - 7

125 = 3x - 7

From here, it should be simple algebra! 

Thanks  for that link Aziz, I have not used the Khan academy much but this looks really good.  

I don't think so. 

I have a poor memory so for me the trick is always to concentrate on understanding as much as possible and back it up with practice, practice and more practice to try and sink it into my brain.  

This is true for all  mathematics and for many other subjects as well.

When you are answering questions with formulas always write the formula and never copy it as you do so.  If you do not know it yet then then you can look at it then cover it over before you write it, you can then check that you got it right.  

Again this is not just calculus advice.

If you are mathematical by nature then hang in there.  Calculus is extremely powerful and so much fun.    

What is the expression for?

Use the x^y key. Or simply use ^ to indicate 'to the power of'.

Example: 3^4 = 81.
