Solve 2(-3^3)+7*(-3^2)+2*-3-3

$$2(- { 3 }^{ 3 } )+7 \times (- { 3 }^{ 2 } )+2 \times -3-3$$

Evaluate

$$-126$$

Solution Steps

Calculate 3 to the power of 3 and get 27.

$$2\left(-27\right)+7\left(-3^{2}\right)+2\left(-3\right)-3$$

Multiply 2 and -27 to get -54.

$$-54+7\left(-3^{2}\right)+2\left(-3\right)-3$$

Calculate 3 to the power of 2 and get 9.

$$-54+7\left(-9\right)+2\left(-3\right)-3$$

Multiply 7 and -9 to get -63.

$$-54-63+2\left(-3\right)-3$$

Subtract 63 from -54 to get -117.

$$-117+2\left(-3\right)-3$$

Multiply 2 and -3 to get -6.

$$-117-6-3$$

Subtract 6 from -117 to get -123.

$$-123-3$$

Subtract 3 from -123 to get -126.

$$-126$$

Factor

$$-126$$
