Assignment:
Simplify the following expression:
3√5xy2 / 3√18x2y
Hint: The first step is to make the radicand a perfect cube (so that exponent equals index) so as to eliminate the radical from the denominator:
3√183 . x3 .y3 = (18)3/3(x)3/3(y)3/3 = 18xy
Note: A radical expression of index n is in simplified form if it has
• no perfect nth powers as factors of the radicand
• no fractions inside the radical
• no radicals in the denominator
Provide complete and step by step solution for the question and show calculations and use formulas.
