@jeromy.
Click the impotant formulas link there you can see 7th formula using that formula we divide log512 by log5.

Please who can solve this log10 2 = 0.3010?

log5512 = log512/log5 = 9log2/log5.
= 9log2/log3+log2.
= 9*0.3010/0.4771+0.3010.
I think this is this the correct procedure as log 2 and log3 values are given. Why we need to go for log 10/2?
= 9log2/log3+log2.
= 9*0.3010/0.4771+0.3010.

Why are they dividing log 512 by log 5?
Is this a formula?

@Nirav.
log512/log5 = 9log2/log(2+3) = 9log2/(log2*log3).
= 9*.3010/(.3010*.4771).
= 9/.4771 >18.
log512/log5 = 9log2/log(2+3) = 9log2/(log2*log3).
= 9*.3010/(.3010*.4771).
= 9/.4771 >18.

Formula:
log a x = log x/log a.
log 5 512 = log 512/log 5.
log a x = log x/log a.
log 5 512 = log 512/log 5.

log(75) = log(70+5).
= log(7*10)+(2+3).
= [log(7)+log(10)]*log(2)*log(3).
= [0.8541+1]*0.3010*0.4771.
= 1.8451*0.3010*0.4771.
= 0.1557.
= log(7*10)+(2+3).
= [log(7)+log(10)]*log(2)*log(3).
= [0.8541+1]*0.3010*0.4771.
= 1.8451*0.3010*0.4771.
= 0.1557.
