Expression to rationalize the numerator and denominator of the above
To rationalize means to reduce a surd to a rational form by multiplying the surd by a suitable surd is know
To rationalize the above surd, we multiply the numerator and denominator by the surd expression at the denominator, which is
<em>Solving further to rationalize the given expression, we have</em>
Multiply
Expand the expression to give
Simplify by dividing numerator and denominator by 3
Expand denominator
Square root of 4 is 2 and square root of is x, so we have
Hence, rationalizing will give
The answer to the proble is (c) the power property. Look at the picture above!
Answer:
<u>(r³)⁻² = r ³ ˣ ⁻² = r ⁻⁶ = 1/r⁶</u>
Step-by-step explanation:
1. Let's recall the rules about the power of a power and the rule of negative exponents to simplify the expression provided:
The first rule tells us that to raise a power to a power, just multiply the exponents. Here you see that r³ raised to the ⁻² power.
The second rule says that any number different than zero, raised to a negative power equals its reciprocal raised to the opposite positive power.
Thus, x ⁻ⁿ = 1/x ⁿ
2. Now, let's find the equivalent after following these rules:
<u>(r³)⁻² = r ³ ˣ ⁻² = r ⁻⁶ = 1/r⁶</u>
