Dear Student,

$$\begin{gathered} Q1. Express 36 in power notation u\sin g prime factorization \\ Prime Factorization, \\ 36=2\times 2\times 3\times 3 \\ = 2^2\times 3^2 Ans \\ Q2. \left(a\right) 810000 in scientific notation \\ 810000 = 8.1 \times {10}^5 \\ \left(b\right) 0.00081 in scientific notation \\ 0.00081 = \frac{8.1}{{10}^4} = 8.1\times {10}^{-4 }Ans \end{gathered}$$
