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.
