Question

write the exponent of 3 in the prime factorisation of 162

Answer 1

$$\begin{gathered} 162=2\times 3\times 3\times 3\times 3=2\times 3^4 \\ \mathrm{Therefore},\mathrm{exponent}\mathrm{of}3\mathrm{in}\mathrm{the}\mathrm{prime}\mathrm{factorisation}\mathrm{of}162\mathrm{is}4. \end{gathered}$$
