Step-by-Step Solution

Answer

Numbers in scientific notation are

(a)$1.29\times {10}^6$

(b)$1.03\times {10}^{-6}$

part (a) Step 1 Given information

$1,290,000$

part (a) Step 2

$$\begin{gathered} 1,290,000=1.29\times 1000000 \\ =1.29\times {10}^6 \end{gathered}$$

part (b) Step 1 Given information

$0.00000103$

part (b) Step 2

$$\begin{gathered} 0.00000103=\frac{1.03}{1000000} \\ =1.03\times {10}^{-6} \end{gathered}$$
