Question

Stuck! *sighs* (-2x^2)(x^-5)^2

Answer 1

you might want to re-write this problem...

Answer 2

\[(-2x^2)(x^-5)^2\]

Answer 3

\[(x - 5)^2 = (x - 5)(x - 5)\]
so \[(x - 5)(x - 5)\]
FOIL that to get what?

Answer 4

\[x^2-10x+25?\]

Answer 5

yeah then we do \[2x^2(x^2 - 10x + 25)\]

Answer 6

Which is \[x^4-20x^3+50x^2?\]

Answer 7

yeah, but idk if your teacher or whoever wants the simplified version or not lol
\[-2x^4-20x^3+50x^2?\] ^^^^^ i think that's what you meant, but you missed the -2

Answer 8

Lol! Thank you so much!

Answer 9

hit that best response if you would :P

Answer 10

May you please help with this one:\[(4/3)^{-6}\]

Answer 11

ok so, since it's to the negative sixth power, we take the reciprocal of the number and then the power becomes positive and we put it in the denominator.
