I need help on this math question i dont understand it.

Answer 1

what don't you understand?

Answer 2

Okay so you are given:
\[\large (5a^3b^2)^2*(-a)^{-2}*b \]
Start by distributing out the exponent on the left and simplifying the negative
\[\Huge (5^2a^{3*2}b^{2*2})*\frac{1}{(-a)^2}*b \]

Now simplify
\[\Large 25a^6b^4*\frac{1}{a^2}*b \]

\[\Large \frac{25a^6b^4*b}{a^2} \]

Combine the b's and subtract the a's
\[\Large 25a^{6-2}b^{4+1} \]
and you end up with
\[\Large 25 a^4b^5\]

Hope that made sense
