Question

been struggling for hours..
Solve:
log(2)3+log(2)x=log(2)(x+7)
please help me solve

Answer 1

\[\log_{2}3+\log_{2}x=\log_{2}(X+7) \]

Answer 2

log(A*B)=logA + logB

now u cn solve?

Answer 3

well i've done \[\log_{2}3+\log_{2}x=\log_{2}(x+7) \]\[3x=(x+7)\]\[2x=7\]\[x=7/2\] but is that the correct math?

Answer 4

yeahh its absolutely correct
as base of log is same on both sides...

Answer 5

so the answer really is x=7/2, thank you

Answer 6

yeahhh absolutely correct...
