please Simplify each expression..
1. (16x^8)^-0.75
= (2^4x^8)^(-3/4)
Taking the 4th root you get:
= (2x^2)^-3
Cubing you get:
= (8x^6)^(-1)
Invert to get:
= 1/(8x^6)
==================================

2. (-64a^9)^4/3
= (-4^3a^9)^(4/3)
Take the cube root to get:
= (-4a^3)^4
Raise to the 4th power to get:
= (256a^12)
===========================
Cheers,
Stan H.
