Given:
The number of 100.
To find:
The given number as an exponential expression with 10 as the base.
Solution:
We have,
Given number = 100
It can be written as
![[\because a^m\cdot a^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Em%5Ccdot%20a%5En%3Da%5E%7Bm%2Bn%7D%5D)
Here, base is 10 and exponent is 2.
Therefore, the given number can be written as 
.
