Video Solution

Solution Steps

00:00 Solve the following problem
00:03 Break down 64 to 4 in third power
00:12 A cube root cancels out a power of three
00:20 Calculate the quotient
00:26 Break down 4 to 2 squared
00:29 The root cancels out the square
00:32 This is the solution

Step-by-Step Solution

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

  • Step 1: Calculate the cube root of 64
  • Step 2: Simplify the fraction 16643\frac{16}{\sqrt[3]{64}}
  • Step 3: Simplify result from step 2\sqrt{\text{result from step 2}}

Let's proceed with each step:
Step 1: The cube root of 64 is calculated as follows:
643=4\sqrt[3]{64} = 4. This is because 43=644^3 = 64.

Step 2: Now, simplify the fraction 164\frac{16}{4}:
164=4\frac{16}{4} = 4.

Step 3: Finally, take the square root of the result from step 2:
4=2\sqrt{4} = 2.

Therefore, the solution to the problem is 22.
