If you want a then the answer will be
a = 8

Actually Welcome to the Concept of the Properties of indices.
Here, we have to prove that, if the above exponential equation are equal or not., let's prove it
1.)L.H.S
a^12*a^4 = a^m*a^n ===> a^(m+n)
hence, a^(12+4) ===> a^(16)
2.) R.H.S
===> a^8*a^8 = a^(8+8) ==> a^(16)
since here, LHS = RHS
so both are equal.
Answer:
Volume of pyramid with square base is 1057.54 m³
Step-by-step explanation:
We are given:
Length of base of pyramid = 14.4 m
Height of pyramid = 15.3 m
We need to find:
Volume of pyramid with square base
The formula used is: 
Where a = base of pyramid and h is height
Putting values and finding volume

So, Volume of pyramid with square base is 1057.54 m³
