Question

1/64=16^4x+3
solve for x
what about this?

Answer 1

2^(-6)=2^[4*(4x+3)]
16x+12=-6
16x=-18
x=-18/16
x=-9/8

Answer 2

i cant get wht u are doing in the first step...

Answer 3

1/64=1/(2^6)=2^(-6)
16=2^4 so 16^(4x+3)=2^[4(4x+3)]

Answer 4

i have expressed both parts of the eq with base 2 so that i can equal exponents

Answer 5

(x^a)^b=X^(ab)
and 1/x^a=X^(-a)

Answer 6

If the two sides have same base, set the exponents equal to each other

Answer 7

hold on let me try another and get back to u to check it

Answer 8
