Video Solution

Solution Steps

00:00 Simplify the following problem
00:03 Every number is to the power of 1
00:14 When we have a root of the order (B) on a number (X) to the power of (A)
00:17 The result equals the number (X) to the power of (A divided by B)
00:20 Apply this formula to our exercise
00:28 When we have division of powers (A/B) with equal bases
00:32 The result equals the common base to the power of the difference of exponents (A - B)
00:35 Apply this formula to our exercise, and subtract between the powers
00:42 Determine the common denominator and proceed to calculate the power
00:53 When we have a negative power
00:57 We can flip the numerator and denominator to obtain a positive power
01:01 Apply this formula to our exercise
01:10 Apply this formula again to our exercise but in the opposite direction
01:13 Convert from the power to the sixth root
01:16 This is the solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Convert the given radical expressions into their equivalent fractional power forms.
  • Step 2: Use the properties of exponents to simplify the expression.
  • Step 3: Convert the result back into a radical form if necessary.

Let's execute these steps:
Step 1: Write 63\sqrt[3]{6} and 6\sqrt{6} in terms of fractional powers:
63=61/3\sqrt[3]{6} = 6^{1/3} and 6=61/2\sqrt{6} = 6^{1/2}.

Step 2: Apply the quotient rule for exponents:
61/361/2=61/31/2=61312=6236=616\frac{6^{1/3}}{6^{1/2}} = 6^{1/3 - 1/2} = 6^{\frac{1}{3} - \frac{1}{2}} = 6^{\frac{2 - 3}{6}} = 6^{-\frac{1}{6}}.

Step 3: Simplify and express back in radical form:
Since a negative exponent denotes the reciprocal, we have 6166^{-\frac{1}{6}} = 1616\frac{1}{6^{\frac{1}{6}}}, which simplifies to 66\sqrt[6]{6}.

Therefore, the expression simplifies to 66\sqrt[6]{6}.

Thus, the solution to the problem is 66\sqrt[6]{6}, which corresponds to choice 3.

Answer

66 \sqrt[6]{6}
