Solve left(3*4right)^2-left(2*4right)^2

$${ \left(3 \cdot 4 \right) }^{ 2 } - { \left(2 \cdot 4 \right) }^{ 2 }$$

Evaluate

$$80$$

Solution Steps

Multiply 3 and 4 to get 12.

$$12^{2}-\left(2\times 4\right)^{2}$$

Calculate 12 to the power of 2 and get 144.

$$144-\left(2\times 4\right)^{2}$$

Multiply 2 and 4 to get 8.

$$144-8^{2}$$

Calculate 8 to the power of 2 and get 64.

$$144-64$$

Subtract 64 from 144 to get 80.

$$80$$

Factor

$$2^{4}\times 5$$
