@yeller33 see, log a log b = log(a/b) and log a + log b = log (ab) remember these 2 formula for ever

log(x)  log(6) = log(15) Add log(6) to each side: log(x) = log(15) + log(6) = log(15 times 6) x = 15 times 6 x = 90

how do you do it if it has a number at the end. = log7+logx=2.... the 2 throws me off.

log7 + logx=2 log(7*x)=2

Does it help?

x=2//7?? ( 7x=2 )

Thus u can write 2 = 2* 1 = \(\large 2* log_{10} 10\) also

log7 + logx=2 log(7*x)=2 10^2 = 7*x 100/7=x

That's how @sauravshakya got the third step

i can write 2 = \(\large \log_{10} (10^2)\)

log7 + logx=2 log(7*x)=2 1/2 log(7x)=1 log{(7x)^1/2} = log10 (7x)^(1/2) = 10 7x = 100 x=100/7

can you two see if i did this one correctly: logx+log8=1 log8*logx=1 8x=1 8x=10^1 10/8
