Video Solution

Solution Steps

00:00 Simplify the following problem
00:03 Every number is to the power of 1
00:10 When we have a root of the order (B) on a number (X) to the power of (A)
00:19 The result equals number (X) to the power of (A divided by B)
00:23 Apply this formula to our exercise
00:31 When we have division of powers (A\B) with equal bases
00:35 The result equals the common base to the power of the difference of exponents (A - B)
00:41 Apply this formula to our exercise, and subtract between the powers
00:49 Determine the common denominator and proceed to calculate the power
00:56 This is the solution

Step-by-Step Solution

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

  • Step 1: Convert the roots to exponent notation
  • Step 2: Apply the quotient of powers rule
  • Step 3: Simplify the expression

Now, let's work through each step:
Step 1: Convert the roots to exponent notation:
4=41/2\sqrt{4} = 4^{1/2} and 43=41/3\sqrt[3]{4} = 4^{1/3}.
Step 2: Calculate the quotient using the rule aman=amn\frac{a^m}{a^n} = a^{m-n}:

41/241/3=4(1/2)(1/3) \frac{4^{1/2}}{4^{1/3}} = 4^{(1/2) - (1/3)}

Step 3: Simplify the exponent:

1/21/3=3626=16 1/2 - 1/3 = \frac{3}{6} - \frac{2}{6} = \frac{1}{6}

Therefore, the expression simplifies to:

416 4^{\frac{1}{6}}

The correct answer is choice 1: 4164^{\frac{1}{6}}.

Answer

416 4^{\frac{1}{6}}
