16-5\left(-2\right)^{2}-2p=4
Calculate -2 to the power of 4 and get 16.
16-5\times 4-2p=4
Calculate -2 to the power of 2 and get 4.
16-20-2p=4
Multiply 5 and 4 to get 20.
-4-2p=4
Subtract 20 from 16 to get -4.
-2p=4+4
Add 4 to both sides.
-2p=8
Add 4 and 4 to get 8.
p=\frac{8}{-2}
Divide both sides by -2.
p=-4
Divide 8 by -2 to get -4.
