Question

Muiltplying 2.5 x 10^10 by 3.5 x 10^-7

Answer 1

Answer:

The value of $\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)$ is 8750

Solution:

$\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)$

$\Rightarrow\left(2.5 \times 10^{10} \times 3.5 \times 10^{-7}\right)$

$\Rightarrow\left(2.5 \times 3.5 \times\left(10^{10} \times 10^{-7}\right)\right)$

$\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)$

$\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)$

$\Rightarrow(2.5 \times 3.5) \times 10^{3}$

$\Rightarrow 8.75 \times 10^{3}$

$\Rightarrow 8.75 \times 1000=8750$
