First, we can use this rule to combine the radicals within the parenthesis:
Next, use this rule for exponents to combine the terms within the radical:
Then, we can use this rule to rewrite the radical into an exponent:
Next, we can use this rule to simplify the inner exponents:
We can use the same rule to reduce the outer exponents:
We can now use this rule to eliminate the negative exponent:
See a solution process belowL
