00:06 Let's solve this math problem together.
00:09 A regular root is called a square root. It has an order of two.
00:14 If we have a number, A, under two roots: one of order B, and another of order C.
00:22 The answer is A, under a root of order B times C.
00:27 Let's use this rule for our exercise.
00:32 Now, if A is to the power of B, under a root order C.
00:43 The answer is A to the power of B divided by C.
00:47 We'll use this formula for our problem.
00:51 And there you have it. That's our 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 .
