Solution Steps

00:06 Let's simplify this problem. Ready?
00:09 Every number here is raised to the power of one.
00:14 And remember, a regular root means the second root.
00:19 If you have a root of order B of a number X, to the power A:
00:24 It equals number X, raised to the power of A divided by B.
00:29 Let's apply this formula to our problem. Try it!
00:33 Dividing powers with the same base. A, divided by B.
00:40 It's the common base to the power of A minus B.
00:44 Use this formula. Subtract the powers.
00:49 Find the common denominator and calculate the power.
01:04 Now, apply it in the reverse. Take your time.
01:08 Convert from power to the fourth root.
01:11 And that's the solution! Great job!

Step-by-Step Solution

Let's simplify the expression 554 \frac{\sqrt{5}}{\sqrt[4]{5}} using the rules of exponents:

  • First, we convert 5 \sqrt{5} to exponent form: 5=51/2 \sqrt{5} = 5^{1/2} .
  • Next, we convert 54 \sqrt[4]{5} to exponent form: 54=51/4 \sqrt[4]{5} = 5^{1/4} .
  • Now, divide the two expressions: 51/251/4=51/21/4 \frac{5^{1/2}}{5^{1/4}} = 5^{1/2 - 1/4} .
  • Subtract the exponents: 51/21/4=52/41/4=51/4 5^{1/2 - 1/4} = 5^{2/4 - 1/4} = 5^{1/4} .

The problem is simplified to 54 \sqrt[4]{5} .

Therefore, the simplified form of the given expression is 54 \sqrt[4]{5} .

Answer

54 \sqrt[4]{5}
