Solve the following exercise:
\( \sqrt{\frac{2}{4}}= \)
Converting to fractional exponents makes division much easier! You can use the simple rule instead of dealing with complicated radical division rules.
Use the rule: . So because the exponent goes on top and the radical index goes on bottom.
Finding the common denominator! The LCD of 3 and 2 is 6. Convert: and , then subtract to get .
No! The problem asks for division: . This means you need to subtract exponents, not add them like you would when multiplying.
Work backwards! Convert back to radicals: . You can also verify your fraction arithmetic: ✓
