Solve the following exercise:
To solve this problem, we'll follow these steps:
Step 1: Convert the given roots into fractional exponents.
Step 2: Simplify the fractional exponents where necessary.
Step 3: Divide using the properties of exponents.
Step 4: Simplify the resulting expression.
Now, let's work through each step:
Step 1: Convert the roots to fractional exponents.
The expression becomes .
Step 2: Simplify each fractional exponent.
We know . So, apply this rule: -
.
.
Step 3: Divide using the properties of exponents.
The division of powers with the same base: . Thus, simplifies to .
Step 4: Simplify the resulting exponent expression.
, (since the negative exponent indicates reciprocal).
Therefore, the solution to the problem is , which matches Choice 2.
Solve the following exercise:
\( \sqrt{\frac{2}{4}}= \)
Converting to fractional exponents makes it easier to apply exponent rules like division. becomes , which is much simpler to work with!
Think of it as "multiply the exponents" when you have a power raised to another power. For , just multiply: .
They're exactly the same thing! . Fractional exponents are just another way to write radicals.
The negative exponent means reciprocal, not negative! . Wait, that's not right in our problem - let me recalculate: actually gives us , but we need to rationalize this to get .
Yes, but it's much harder! You'd need to work directly with the radical properties, which can get confusing. The fractional exponent method is the most reliable approach.
