Solution Steps

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent. Subtract 2 from 4 to get 2.

$$\sqrt{\left(\frac{2+2^{2}\times 3-\frac{\frac{24}{6}}{2}}{2^{2}}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Calculate 2 to the power of 2 and get 4.

$$\sqrt{\left(\frac{2+4\times 3-\frac{\frac{24}{6}}{2}}{2^{2}}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Multiply 4 and 3 to get 12.

$$\sqrt{\left(\frac{2+12-\frac{\frac{24}{6}}{2}}{2^{2}}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Add 2 and 12 to get 14.

$$\sqrt{\left(\frac{14-\frac{\frac{24}{6}}{2}}{2^{2}}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Express \frac{\frac{24}{6}}{2} as a single fraction.

$$\sqrt{\left(\frac{14-\frac{24}{6\times 2}}{2^{2}}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Multiply 6 and 2 to get 12.

$$\sqrt{\left(\frac{14-\frac{24}{12}}{2^{2}}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Divide 24 by 12 to get 2.

$$\sqrt{\left(\frac{14-2}{2^{2}}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Subtract 2 from 14 to get 12.

$$\sqrt{\left(\frac{12}{2^{2}}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Calculate 2 to the power of 2 and get 4.

$$\sqrt{\left(\frac{12}{4}\right)^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Divide 12 by 4 to get 3.

$$\sqrt{3^{2}+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Calculate 3 to the power of 2 and get 9.

$$\sqrt{9+2\left(3^{2}-2^{2}\right)-2^{3}+3^{2}-5}$$

Calculate 3 to the power of 2 and get 9.

$$\sqrt{9+2\left(9-2^{2}\right)-2^{3}+3^{2}-5}$$

Calculate 2 to the power of 2 and get 4.

$$\sqrt{9+2\left(9-4\right)-2^{3}+3^{2}-5}$$

Subtract 4 from 9 to get 5.

$$\sqrt{9+2\times 5-2^{3}+3^{2}-5}$$

Multiply 2 and 5 to get 10.

$$\sqrt{9+10-2^{3}+3^{2}-5}$$

Calculate 2 to the power of 3 and get 8.

$$\sqrt{9+10-8+3^{2}-5}$$

Subtract 8 from 10 to get 2.

$$\sqrt{9+2+3^{2}-5}$$

Add 9 and 2 to get 11.

$$\sqrt{11+3^{2}-5}$$

Calculate 3 to the power of 2 and get 9.

$$\sqrt{11+9-5}$$

Add 11 and 9 to get 20.

$$\sqrt{20-5}$$

Subtract 5 from 20 to get 15.

$$\sqrt{15}$$
