Answer 2

d) 5.88 × 10⁻⁹

Step-by-step explanation:

`\rightarrow \sf \left(1.2\cdot 10^7\right)\left(4.9\cdot 10^2\right)`

`\sf apply \ exponent \ rule : a^b + a^c = a^(b + c)`

`\rightarrow \sf 1.2\cdot \:4.9\cdot \:10^(7)\cdot \:10^(2)`

`\rightarrow \sf 1.2\cdot \:4.9\cdot \:10^(7+2)`

`\rightarrow \sf 1.2\cdot \:4.9\cdot \:10^9`

`\rightarrow \sf 5.88 \cdot \:10^9`
