Question 993545
.
4logbase10(0.9)=logbase10(x)
calculate the value of x with full method show.
-----------------------------------------------------


{{{4*log(10,(0.9))}}} = {{{log(10,(x))}}}     ----->


{{{log(10,(0.9^4))}}} = {{{log(10,(x))}}}     ----->


{{{0.9^4}}} = {{{x}}}                     ----->


x = {{{0.9^4}}} = 0.6561.
