Question
I'm studying to take a math placement exam and it has been a long time since I've taken a math class. Can someone please give me a step to step solution of these:
A.Simplify:
8x/[2^(x-1)] Answer = 2^(2x+1)
B.Simplify:
(2^x)*[4^(x-1)] Answer = 2^(3x-2)
A.Simplify:
8x/[2^(x-1)] Answer = 2^(2x+1)
B.Simplify:
(2^x)*[4^(x-1)] Answer = 2^(3x-2)

Huh?
x (2^3) 2^(-x+1)
x (2^-x)( 16)
16 x/2^x
I bet you mean
8^x [2^(-x+1)]
2^3x [2^-x 2^1]
2^[2x+1]
2^x 2^(2x-2)
2^(3x-2)
x (2^3) 2^(-x+1)
x (2^-x)( 16)
16 x/2^x
I bet you mean
8^x [2^(-x+1)]
2^3x [2^-x 2^1]
2^[2x+1]
2^x 2^(2x-2)
2^(3x-2)
