THANK YOU SO MUCH

Jackson has the following bills:

3 X $1=$3

2 X $5=$10

3 X $10=$30

$3+$10+$30=$43 in total

Scientific nottion is used to make numbers more managable. The numbers must fall between 1 and 9.999999 then you multiply by 10 to however many decimal places you moved it to get the number within those restrictions. so the scientic notation is 4.0999932 X 10 to the 15th power

The answer is N=0.99747959

There is several ways to do this. But one easy way would be to solve the left side first.

For example:

5/6=0.83333333333333333333...

that means X^72=0.83333333...

Now we have a base from which to start.

An easy way is to do the 72nd root of the function. On your calculator you should see something that looks like 

This. --->\(\sqrt[x]{}\)

you should type 72 then press that button and enter 0.8333333333333... and you will find the answer to N. Another way you can do that is in grade 12 Advanced functions in Canada... But im sorry at the moment i dont remember as to how.

This way displayed above should easily get you the right answer.
 

My exact button presses on my calculator is 5 ab/c 6 = ab/c until decimals are shown.  Then i delete the answer so i can type the next function in.Then I do 72\(\sqrt[x]{}\)Ans which means \(\sqrt[72]{0.833333333333}\) Then you should find your answer.

0/4 Does not equal 32 

 If it matters 128/4=32

0 divided by anything equals 0. This is because you cannot break 0 into groups. You should think of division in terms of breaking things into evenly distributed goods. since you are trying to break 0 into 4 groups. Since 0 has no value all groups would be even at 0. 0+0+0+0=0

x(x-8)=(x^2-8x)

*NOTE* Sorry for the messy writing above... I learned how hard it was to write in paint.***

You can solve this by breaking it up into different sections. first make sure you distribute the 8 along all of the possible combinations.

For example:

(x*x) (x*-8)

now we know that x*x= x^2 due to X^2 literally meaning X*X. We also know that X*8=8X but since the 8 is a negative the negative should carry over. so the section should equal -8X. now combine all the sections back together and you should get your answer of (X^2-8X).

Now keep in mind if the question was (x-3)(x+5) you would break it into (X*X)(X*5)(-3*X)(-3*5) You should solve each section. (X^2)(5X)(-3X)(-15) Now combine all of the sections together.  X^2+5X-3X-15. Now simplify the answer X^2+2x-15.

*NOTE* Make sure that all of the combinations are satisfied.

Correct.....you got the right answer  !!!

Very nice, Joshie17   !!!!!

Thanks :-)

You can get this by collecting easier additions.

For example you start with this

$0.84 + $1.50+ $10.99+ $3.00+ $1.00+ $5.00=

Reorganize it to make the edition easier. (Collect the whole numbers together.)

($3.00+ $1.00+ $5.00)+1.50+10.99+$0.84

This makes it easier to start. 

Add all the whole numbers first

3+1+5=9

Now move onto the decimal answers. An easy way to think of this is by taking .01 away from 1.5 or 0.84 and adding it to the 10.99 to make 11. This makes another whole number which you can add to the total,

9+11=20

Now all you have left is either 1.49+0.84 or 1.50+0.83

Now solve one of the 2 equations.  I would personally fo to the 

1.50+0.83 because 1.5 is the easiest to work with. 

you can subtract 0.50 from 0.83 to make 1.5 a whole number.

0.83-0.50=0.33

1.5+0.5=2

that means you found another whole number due to the 0.5 being added onto the 1.5.

add the whole numbers together 20+2=22.

Now all you have left is the whole number and the small decimal. just attach the small decimal to the whole number such as 22.33

$22.33

simplify 3^16/3^8=^16 -^8=3^8

find quotient  3^16/3^8=3^8=6561

the Answer should be 0. This is due to b.e.d.m.a.s. First you start by solving inside of the brackets first. so 5^2=25.

9-8-7-6-5+3(4)+2(25)/10

Next you have to solve all of the multiplication starting from the left. 

9-8-7-6-5+(12)+2(25)/10

Then the next multiplication

9-8-7-6-5+(12)+(50)/10

Now according to bedmas division is before addition and subtraction so you solve the division.

50/10=5

9-8-7-6-5+12+5

Then solve the rest by adding and subtracting

9-8-7-6-5+12+5=0

*NOTE* keep in mind you solve for whatever comes first... Division or multiplication. In this case All of the multiplication came first so you divided last. If the equation was 

3583551222729 ;-P

Exactly you don't know how much it costs to go forward

6561 is the answer

0 is the answer

50 + 1/4=50 1/4=201/4

201 / 4

SHUT UP AND GO BACK TO YOUR BOOKS!!

Hallo guest,do you mean thus?

1/3^(x+2)=1/81

You invent a time machine which can travel to the past. For every 10 years it goes back, it consumes 100 Kg Plutonic energy. The Plutonic costs $10 per Kg. You only have $3000 in the bank so at most how far can you go back and return to the present?

Traveling back 10 years costs :    100kg x $10/kg = $1000

So :   

[$3000/ $1000]  x 10 years =   30 years back   [I'm assuming that it costs  nothing to go "forward" ]

Notice that  :

1 = 10ⁿ / 10ⁿ =   10^n-n = 10⁰

We can use the tangent inverse to answer this  :

tan^-1 ( 11 / 90)   ≈ 6.97°
