Answer:</h2>
See the attached figure for solution
Given:
Consider the given equation is

To find:
The missing value in the given equation and complete the equation.
Solution:
We have,

Taking LHS, we get

![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)

and,

Let the missing value be k.
For each equation LHS=RHS.


Therefore, the missing value is 10 and the complete equation is
.
