400=k\times 3\times 64
Calculate 8 to the power of 2 and get 64.
400=k\times 192
Multiply 3 and 64 to get 192.
k\times 192=400
Swap sides so that all variable terms are on the left hand side.
k=\frac{400}{192}
Divide both sides by 192.
k=\frac{25}{12}
Reduce the fraction \frac{400}{192} to lowest terms by extracting and canceling out 16.
