Determine the value of X if (211) base x = (152) base 8, how to do this?

we translate the following statement given in terms of logarithms. 211 base x can be expressed into log 211 / log x while 152 base 8 can be expressed int o log 152 over log 8. In this case,

log 211 / log x = log 152 / log 8log x = 0.962x = 10^0.962 = 9.1632
