Question

How do you write `10^5` in decimal form?

Answer 1

`100000`

Explanation:

A power is a reiterated multiplication. So, `10^5=10*10*10*10*10`. And as you know, multiplying by `10` means to add a zero at the end of the number.

This also means that `10^k` is simply a one followed by `k` zeroes.
