Video Solution

Solution Steps

00:00 Find the value X
00:06 Solve the power multiplication
00:16 Multiply the order of the first root by the order of the second root
00:22 Apply the order that we obtained as a root to our number
00:27 Apply this formula to our exercise
00:32 When we have a root of order (C) on a number (A) to the power of (B)
00:39 The result equals number (A) to the power of (B divided by C)
00:43 Apply this formula to our exercise
00:52 Break down 144 to 12 squared
00:57 The root cancels out the square
01:02 This is the solution

Step-by-Step Solution

To solve this equation, we will follow these steps:

  • Step 1: Simplify the left side of the equation 144 \sqrt{144} .
  • Step 2: Simplify the right side of the equation x3053 \sqrt[3]{\sqrt[5]{x^{30}}} .
  • Step 3: Equate the simplified expressions and solve for x x .

Let us go through these steps:

Step 1: Simplify the left side:

The left side of the equation is 144 \sqrt{144} , which simplifies to 12 12 , because 144=12 \sqrt{144} = 12 .

Step 2: Simplify the right side:

The expression on the right is x3053 \sqrt[3]{\sqrt[5]{x^{30}}} . Let's simplify it step by step:

  • First, simplify x305 \sqrt[5]{x^{30}} :
    - Using the rule amn=am/n \sqrt[n]{a^m} = a^{m/n} , we have x305=x30/5=x6 \sqrt[5]{x^{30}} = x^{30/5} = x^6 .
  • Next, simplify x63 \sqrt[3]{x^6} :
    - Again using the same rule, x63=x6/3=x2 \sqrt[3]{x^6} = x^{6/3} = x^2 .

Step 3: Equate and solve:

From the previous steps, we get:

12=x2 12 = x^2

Therefore, the solution to the equation is:
x2=12 x^2 = 12 .

Answer

x2=12 x^2=12
