How do you solve 8^x = 1/2 and 4x^4y^5z/6wxy^-3z^3?

Question

worked out please?

Answer 1

Use log base 2:-
log 8^x = log (1/2)
x log 8 = log(1/2)
x log 8 = - 1
x = - 1 / 3

Answer 2

= 1

Answer 3

What a monster! You'll need to use logarithms, but your answer is going to be in terms of w, y, and z because you don't have enough equations for a complete solution.

By the way, x=-1/3 , but you'll have to do the math.
