Evaluate integers raised to positive rational exponents

Full solution

Q.

\sqrt{75 x^{8}}

Identify Components: Identify the components of the expression. $\newline$ We have the square root of $75x^{8}$ , which can be written as $(75x^{8})^{1/2}$ .
Break Down Factors: Break down the expression into prime factors and perfect squares. $\newline$ $75$ can be factored into $3 \times 5 \times 5$ , and $x^{8}$ is already a perfect square since $8$ is an even number. $\newline$ So, $(75x^{8})^{1/2} = (3 \times 5^2 \times x^{8})^{1/2}$ .
Apply Square Root: Apply the square root to the factors. $\newline$ The square root of $5^2$ is $5$ , and the square root of $x^{8}$ is $x^{8/2} = x^{4}$ . $\newline$ So, $(3 \times 5^2 \times x^{8})^{1/2} = 5x^{4} \times (3)^{1/2}$ .
Simplify Remaining Root: Simplify the remaining square root. The square root of $3$ cannot be simplified further, so we leave it as is. Therefore, the final simplified form is $5x^{4} \sqrt{3}$ .
