(-a^3b^2*-a^-2b^-3)^-2/2a^2b^-3
= a^4b^9/2a^8b^4
=b^5/2a^4
so your answer is b^5/2a^4
There are 8 big fish for every 10 small fish, ..... 5 small fish.
The equation for that is V = 1/2 A x C x H
![\sqrt[8]{48^4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B8%5D%7B48%5E4%7D%20)
can be rewritten as

to the

power:

Now, applying exponent rules (multiply exponent inside parentheses by the one outside parentheses), we get:

This is equivalent to

, so now, we just simplify:

So:
