Solve 18-sqrt{81}+9*3^4-(3-2+9)div2

$$18 - \sqrt { 81 } + 9 \cdot 3 ^ { 4 } - ( 3 - 2 + 9 ) \div 2$$

Evaluate

$$733$$

Solution Steps

Calculate the square root of 81 and get 9.

$$18-9+9\times 3^{4}-\frac{3-2+9}{2}$$

Subtract 9 from 18 to get 9.

$$9+9\times 3^{4}-\frac{3-2+9}{2}$$

Calculate 3 to the power of 4 and get 81.

$$9+9\times 81-\frac{3-2+9}{2}$$

Multiply 9 and 81 to get 729.

$$9+729-\frac{3-2+9}{2}$$

Add 9 and 729 to get 738.

$$738-\frac{3-2+9}{2}$$

Subtract 2 from 3 to get 1.

$$738-\frac{1+9}{2}$$

Add 1 and 9 to get 10.

$$738-\frac{10}{2}$$

Divide 10 by 2 to get 5.

$$738-5$$

Subtract 5 from 738 to get 733.

$$733$$

Factor

$$733$$
