Solve 7.5*(7.5-5)*(7.5-4)(7.5-6)

$$7.5 \times (7.5-5) \times (7.5-4)(7.5-6)$$

Evaluate

$$98.4375$$

Solution Steps

Subtract 5 from 7.5 to get 2.5.

$$7.5\times 2.5\left(7.5-4\right)\left(7.5-6\right)$$

Multiply 7.5 and 2.5 to get 18.75.

$$18.75\left(7.5-4\right)\left(7.5-6\right)$$

Subtract 4 from 7.5 to get 3.5.

$$18.75\times 3.5\left(7.5-6\right)$$

Multiply 18.75 and 3.5 to get 65.625.

$$65.625\left(7.5-6\right)$$

Subtract 6 from 7.5 to get 1.5.

$$65.625\times 1.5$$

Multiply 65.625 and 1.5 to get 98.4375.

$$98.4375$$

Factor

$$\frac{7 \cdot 3 ^ {2} \cdot 5 ^ {2}}{2 ^ {4}} = 98\frac{7}{16} = 98.4375$$
