Solve 65*3,4^2/2-65*4^2/2=

$$\frac { 65 \cdot 3,4 ^ { 2 } } { 2 } - \frac { 65 \cdot 4 ^ { 2 } } { 2 } =$$

Evaluate

$$1040$$

Solution Steps

Multiply 65 and 3 to get 195.

$$\frac{195\times 4^{2}}{2}-\frac{65\times 4^{2}}{2}$$

Calculate 4 to the power of 2 and get 16.

$$\frac{195\times 16}{2}-\frac{65\times 4^{2}}{2}$$

Multiply 195 and 16 to get 3120.

$$\frac{3120}{2}-\frac{65\times 4^{2}}{2}$$

Divide 3120 by 2 to get 1560.

$$1560-\frac{65\times 4^{2}}{2}$$

Calculate 4 to the power of 2 and get 16.

$$1560-\frac{65\times 16}{2}$$

Multiply 65 and 16 to get 1040.

$$1560-\frac{1040}{2}$$

Divide 1040 by 2 to get 520.

$$1560-520$$

Subtract 520 from 1560 to get 1040.

$$1040$$

Factor

$$2^{4}\times 5\times 13$$
