The value of x has to be determined given that `log_5 x^18 = 360`

Use the property of logarithm log a^b = b*log a

`log_5 x^18 = 360`

=> `18*log_5 x = 360`

=> `log_5 x = 360/18`

=> `log_5 x = 20`

=> x = 5^20

The value of x = 5^20

as usual log=a^b

solution: 18.log 5 x=360

                       5 x =360/18

                       5 x =20

                         x =5^20
