Question

What is $2$ raised to the power of $100$?

Answer 1

Exponent power of a number.

By laws of exponent,

$a^m=a\times a\times a\times a\times .....\times a(\mathrm{m}\mathrm{times})$

Where $a$ is base and $m$ is power.

$$\begin{gathered} \therefore 2^{100}=2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times .....\times 2(100\mathrm{times}) \\ \Rightarrow =1.27\times {10}^{30} \end{gathered}$$

Hence, the required value is $1.27\times {10}^{30}$.
