Solve 1(-9)^2+7(-9)^5-9/-2*(-9)+7

$$\frac { 1 ( - 9 ) ^ { 2 } + 7 ( - 9 ) ^ { 5 } - 9 } { - 2 \times ( - 9 ) + 7 }$$

Evaluate

$$-\frac{413271}{25}=-16530.84$$

Solution Steps

Calculate -9 to the power of 2 and get 81.

$$\frac{1\times 81+7\left(-9\right)^{5}-9}{-2\left(-9\right)+7}$$

Multiply 1 and 81 to get 81.

$$\frac{81+7\left(-9\right)^{5}-9}{-2\left(-9\right)+7}$$

Calculate -9 to the power of 5 and get -59049.

$$\frac{81+7\left(-59049\right)-9}{-2\left(-9\right)+7}$$

Multiply 7 and -59049 to get -413343.

$$\frac{81-413343-9}{-2\left(-9\right)+7}$$

Subtract 413343 from 81 to get -413262.

$$\frac{-413262-9}{-2\left(-9\right)+7}$$

Subtract 9 from -413262 to get -413271.

$$\frac{-413271}{-2\left(-9\right)+7}$$

Multiply -2 and -9 to get 18.

$$\frac{-413271}{18+7}$$

Add 18 and 7 to get 25.

$$\frac{-413271}{25}$$

Fraction \frac{-413271}{25} can be rewritten as -\frac{413271}{25} by extracting the negative sign.
