70=k\times 15\times 4
Calculate 2 to the power of 2 and get 4.
70=k\times 60
Multiply 15 and 4 to get 60.
k\times 60=70
Swap sides so that all variable terms are on the left hand side.
k=\frac{70}{60}
Divide both sides by 60.
k=\frac{7}{6}
Reduce the fraction \frac{70}{60} to lowest terms by extracting and canceling out 10.
