Answer 2

Answer:

d) 5.88 × 10⁻⁹

Explanation:

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

$\sf apply \ exponent \ rule : a^b + a^c = a^{b + c}$

$\rightarrow \sf 1.2\cdot \:4.9\cdot \:10^{7}\cdot \:10^{2}$

$\rightarrow \sf 1.2\cdot \:4.9\cdot \:10^{7+2}$

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

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