Answer: C
Explanation:
√55x⁷y⁶/11x¹¹y⁸
→ 55/11 = 5
→ x⁷/x¹¹= x⁷⁻¹¹= x⁻⁴
→ y⁶/y⁸= y⁶⁻⁸= y⁻²
→ √5/x⁴y²
→ √5/x²y
If the exponent is a negative, the base is the reciprocal of itself with a positive exponent.
Ex: 6⁻² = 1/6² = 1/36
The square root of an exponent with a positive, even power is half of that power.
Ex: √x⁴ = x²
