If

Question

P=(64)^-2
Q=1/(16)^1/3
R=8root2

Express pqr as
i) a power of 2
ii) a power of 4

Answer 1

p = 2^-12 = 4^-6
q = 2^-(4/3) = 4^(-2/3)
r = 8*2^(1/2) = 2^(7/2) = 4^(7/4)

Now just add up the powers for the product.

Answer 2

The power of 2 and power of 4 are separate questions. So why are we adding the powers?

Answer 3

Come on, guy.
Add the powers of 2 for one answer; add the powers of 4 for the other.

I was just showing how each number could be expressed either as a power of 2 or a power of 4.

Sheesh.
