Video Solution

Solution Steps

00:00 Solve the following problem
00:03 A 'regular' root is of the order 2
00:08 When we have a number (A) in a root of the order (B) in a root of the order (C)
00:16 The result equals the number (A) in a root of the order of their product (B times C)
00:21 We will apply this formula to our exercise
00:26 Let's calculate the of order multiplication
00:37 When we have a number (A) to the power of (B) in a root of the order (C)
00:41 The result equals number (A) to the power of their quotient (B divided by C)
00:44 We will apply this formula to our exercise
00:53 This is the solution

Step-by-Step Solution

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

  • Step 1: Simplify the inner square root.
  • Step 2: Apply the formula for nested roots.
  • Step 3: Compute the fifth root.

Now, let's work through each step:

Step 1: Calculate the inner square root.
We have 1024\sqrt{1024}. We know that 1024=2101024 = 2^{10}, so 1024=210\sqrt{1024} = \sqrt{2^{10}}.

Applying the property of roots, 210=2102=25=32\sqrt{2^{10}} = 2^{\frac{10}{2}} = 2^5 = 32.

Step 2: Now, apply the fifth root to the result from step 1.
We need to find 325\sqrt[5]{32}.

Step 3: Simplify using the properties of exponents.
From 325=255\sqrt[5]{32} = \sqrt[5]{2^5}, we have 255=21=22^{\frac{5}{5}} = 2^1 = 2.

Therefore, the solution to the problem is 2 2 .
