Solve x-2^3div2*3/40

$$\frac { x - 2 ^ { 3 } \div 2 \times 3 } { 40 }$$

Evaluate

$$\frac{x-12}{40}$$

Solution Steps

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent. Subtract 1 from 3 to get 2.

$$\frac{x-2^{2}\times 3}{40}$$

Calculate 2 to the power of 2 and get 4.

$$\frac{x-4\times 3}{40}$$

Multiply 4 and 3 to get 12.

$$\frac{x-12}{40}$$

Expand

$$\frac{x}{40}-\frac{3}{10}$$
