Answer 1

Given that decimal number,

$\Rightarrow 2.7\times {10}^{12}$ and $1.5\times {10}^8$

Now multiply of,$2.7\times {10}^{12}$ and $1.5\times {10}^8$

$\Rightarrow 2.7\times {10}^{12}\times 1.5\times {10}^8$

$\Rightarrow 2.7\times 1.5\times {10}^{12}\times {10}^8$

$\Rightarrow 4.05\times {10}^{12+8}$

$\Rightarrow 4.05\times {10}^{20}$
