Question

2=log x +log (x+48) solve

Answer 1

ok, so log(a) + log(b) = log(ab)

this means we can group together on the RHS

2 = log(x(x+48))

now we want to get rid of the logs

assuming this is the common base 10 logarithm
we raise 10 to the power of each side:
10^2 = 10^log(x(x+48))

now the log and the 10^ cancel

leaving

100 = x(x+48)

do you follow the steps up to there?

Answer 2

can't be more clear than that...

Answer 3

:D

i could have explained why they cancel i suppose

Answer 4

Thanks Still a little confused
