Use change of base to rewrite the expression, log5 16

When I solved this, I got log10 16 / log10 5

But when checking it on mathway I got log 16 / log 5

Could someone explain this?

it's a semantics thing ... if no base is indicated , 10 is assumed

the base does not matter. log<sub>b</sub>16/log<sub>b</sub>5 = log<sub>5</sub>16
