The equation `5^x = 17` has to be solved for x.

Take the logarithm to base 10 of both the sides

`log_10(5^x) = log_10 17`

Use the relation `log_10 a^b = b*log_10 a`

`x*log_10 5 = log_10 17`

`x = (log_10 17)/(log_10 5)`

The approximate value of x is 1.76

Taking log on both side


Since `loga^m=mloga`




`x approx 1.7604 `
