xlog(3.7) = log(37)
x = log(37)/log(3.7)
= 2.7599 (approx)

Do you mean 3.7*10^x=37? In that case, x=1

I am assuming you are asked to solve for x? If so, you should write that.
take logarithm of both sides
log(3.7^x)=log(37)
x log (3.7) = log(37)
x= log 37/log(3.7)
aproximately 2.759938342

if 3.7^x=37,
then log(base 3.7)of 37 = x

x.log 3.7 = log 37
x = log 37 / log 3.7
x = 2.76 (to 2 dec. places)

3.7^x = 37
take log for both sides
log 3.7^x = log37
use exponent rule of log: loga^x = x loga
x log3.7 = log37
divide log3.7 for both side
x = log37 / log3.7

xlog3.7=log37
x=log37/log3.7=2.76
