Question

NO SILLY ANSWERS PLEASE Can someone help me with this?

Answer 1

Keep in mind that, when the logarithm base is not explicitly written, base 10 is assumed, therefore,

$\bf \textit{Logarithm Cancellation Rules}\\\\ log_a a^x\implies x\qquad \qquad a^{log_ax}=x\\\\ -------------------------------\\\\ 10^{log(3)}+log(100)\implies 10^{log_{10}(3)}+log_{10}(100)\implies 3+log_{10}(10^2) \\\\\\ 3+2\implies 5$
