Solve -10-12(15^2)1/2+217.3(15-10)

$$-10-12( { 15 }^{ 2 } ) \frac{ 1 }{ 2 } +217.3(15-10)$$

Evaluate

$$-273.5$$

Solution Steps

Calculate 15 to the power of 2 and get 225.

$$-10-12\times 225\times \frac{1}{2}+217.3\left(15-10\right)$$

Multiply 12 and 225 to get 2700.

$$-10-2700\times \frac{1}{2}+217.3\left(15-10\right)$$

Multiply 2700 and \frac{1}{2} to get \frac{2700}{2}.

$$-10-\frac{2700}{2}+217.3\left(15-10\right)$$

Divide 2700 by 2 to get 1350.

$$-10-1350+217.3\left(15-10\right)$$

Subtract 1350 from -10 to get -1360.

$$-1360+217.3\left(15-10\right)$$

Subtract 10 from 15 to get 5.

$$-1360+217.3\times 5$$

Multiply 217.3 and 5 to get 1086.5.

$$-1360+1086.5$$

Add -1360 and 1086.5 to get -273.5.

$$-273.5$$

Factor

$$-273.5$$
