Solve 8+9-13*9^3/4

$$8+9- \frac{ 13 \times { 9 }^{ 3 } }{ 4 }$$

Evaluate

$$-\frac{9409}{4}=-2352.25$$

Solution Steps

Add 8 and 9 to get 17.

$$17-\frac{13\times 9^{3}}{4}$$

Calculate 9 to the power of 3 and get 729.

$$17-\frac{13\times 729}{4}$$

Multiply 13 and 729 to get 9477.

$$17-\frac{9477}{4}$$

Convert 17 to fraction \frac{68}{4}.

$$\frac{68}{4}-\frac{9477}{4}$$

Since \frac{68}{4} and \frac{9477}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{68-9477}{4}$$

Subtract 9477 from 68 to get -9409.

$$-\frac{9409}{4}$$

Factor

$$-\frac{9409}{4} = -2352\frac{1}{4} = -2352.25$$
