The simplified form is ⇒ A
Step-by-step explanation:
To simplify a root divide the power of the variable by 2 to cancel itFactorize the coefficient of the variable and take out the repeated factor twice out the root
Let us solve the question
∵ The expression is
→ At first, divide simplify the coefficient of the variable
∵
∵ 36 = 6 × 6 and 25 = 5 × 5
→ 6 and 5 repeated twice then the can go out the root one 6 and one 5
∴
→ Let us use the exponent rule with division
∵
→ To cancel the root divide the power by 2
∵ -20 ÷ 2 = -10
∴
∴ = ×
→ To change the power of x from (-) to (+) reciprocal x
∴
∴ =
∴ The simplified form is
