9\times 8=K\times 2\times 3^{2}
Multiply both sides by 8.
72=K\times 2\times 3^{2}
Multiply 9 and 8 to get 72.
72=K\times 2\times 9
Calculate 3 to the power of 2 and get 9.
72=K\times 18
Multiply 2 and 9 to get 18.
K\times 18=72
Swap sides so that all variable terms are on the left hand side.
K=\frac{72}{18}
Divide both sides by 18.
K=4
Divide 72 by 18 to get 4.
