anonymous one year ago i need help solving this pleasee 4^2x = 32

1. YoloShroom

So is this your question? $4^{2x}=32$

2. anonymous

4^2= 16, because 4*4 is 16. Now, you divide both sides by 16. $\frac{ 16x }{ 16 }=\frac{ 32 }{ 16 }$ 16x divided by 16 cancels out. NOw, what would 32 divided by 16 be?

3. Nnesha

it's 4 to the (2x) power :=)

XD I JUST noticed that!

it's okay and selly somebody asked a question you should answer it.

write both sides of the equation as powers of 2. $4^{2x} = 32 ~~~or~~~~(2^2)^{2x} = 2^5$ so after multiplying the powers you get $2^{4x} = 2^5$ equate the powers so 4x = 5 and just solve for x

yes thats my question sorry guys i had to take a moment to change my babies diapers ! anyways but oh ok i see whats your saying. so my answer is x=0.8

9. anonymous

or just x=5/4 actually
