Question

I can't remember the steps to do this problem:
(-4x)^2(3x^8)^2

Answer 1

PEMDAS is needed here. So, first, square the terms in the parenthesis.

Answer 2

What do you get?

Answer 3

-16x and 9x^8?

Answer 4

square the entire term (-4x) and you get....

Answer 5

\[\Large (-4x)(-4x) \times (3x^8)(3x^8)\]
Can u solve now?

Answer 6

Ah! Lemme give it a shot!

Answer 7

16x * 9x^16?

Answer 8

Almost. What is x*x?

Answer 9

1?

Answer 10

Same rule as when you did (x^8) * (x^8)

Answer 11

So the answer is 144x^8 ?

Answer 12

Sorry, 144x^16

Answer 13

144x^18

Answer 14

How do you get 18 as an exponent?

Answer 15

I am sure u missed to add the "left exponents"

Answer 16

(-4x)(-4x)

-4 * - 4 = 16
x * x = x^2

Answer 17

Oh! Yes I did miss that part! I see now and thank you all so very much :)
