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 
.

Base x height divided by 2
10x8=80
80÷2=40
area=40
Hey there!
Let's pull out the multiples of each number and see which ones fall in line first.
9,18
6,12,18
The LCM is 18. Therefore, answer B and D are incorrect. A is incorrect because 9 * 6 is 54. Therefore, the answer is C.
I hope this helps!
