Question

Simplify.


A.

B.

C.

D.

Answer 1

You can select the correct answer by just knowing what is \[-5^{3}\](-5)(-5)(-5) is what?

Answer 2

@radar , Not quite , 2 answer with -125 , just must know at least that (p^4)^3 = P^12

Answer 3

Well maybe not solve, but at least bring it down to just two probable answers .

Answer 4

Hi, TrojanPoem

Answer 5

You can lock it down to just one answer by doing the \[(p ^{4})^{3}\]

Answer 6

Use the rule that\[(x ^{a})^{b}= x ^{ab}\]

Answer 7

Im super lost and if I could put this into a calculator I would...lol...

Answer 8

did you understand that \[-5^{3}=-5\times-5\times-5=-125\]??

Answer 9

This narrows the choices down to A. or C.

Answer 10

@ciaramahogany , You could xD


I used to do that, assume P = const , z = const , u = const ( no 1 , no zero)

P = 2 , Z = 3, u = 4

(-5 * (2)^4 * (3)^6 * 4)^3 = -1.269 * 10^16 (the damn calculator says)

Now check each answer by plugging the values

A) -125 * (2)^12 * (3)^18 * (4)^3 =- 1.269 x 10^16 , ( the same as what we got up)
B) , C) , D) are different from 1.269 * 10^16

You are free to assume any number as long as it's not 1 or zero or that way the power is neglected.

Answer 11

Neat trick @TrojanPoem
