Solution Steps

00:00 Simplify the following problem
00:03 When there's a root of a fraction (A divided by B)
00:06 We can write it as root of the numerator (A) divided by root of the denominator (B)
00:10 We'll apply this formula to our exercise
00:19 When we have a root of the multiplication (A times B)
00:24 We can also split it into root of (A) multiplied by the root of (B)
00:28 We'll apply this formula to our exercise
00:38 Break down 144 to 12 squared
00:47 Break down 9 to 3 squared
00:54 The root of any number (A) squared cancels out the square
00:58 Apply this formula to our exercise and proceed to cancel out the squares
01:11 Break down X to the power of 10 into X to the power of 5 squared
01:15 Break down X to the power of 4 into X squared squared
01:24 Simplify the squares with the roots
01:33 Break down 12 into factors of 4 and 3
01:37 Break down X to the power of 5 into factors of X cubed and X squared
01:45 Simplify wherever possible
01:49 This is the solution

Step-by-Step Solution

To solve this problem, we will proceed as follows:

  • Step 1: Simplify the expression inside the square root.
  • Step 2: Apply the square root to both the numerator and the denominator separately.
  • Step 3: Simplify the resulting expression.

Let's go through each step:

Step 1: Simplify the fraction 144x109x4\frac{144x^{10}}{9x^4}.

In the given expression 144x109x4\frac{144x^{10}}{9x^4}, separate the numeric part from the variable part:

1449=16\frac{144}{9} = 16 and x10x4=x104=x6\frac{x^{10}}{x^4} = x^{10-4} = x^6.

Thus, the expression simplifies to 16x616x^6.

Step 2: Apply the square root property ab=ab\sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}} to each part.

144x109x4=16x6\sqrt{\frac{144x^{10}}{9x^4}} = \sqrt{16x^6}.

Now separate into numeric and variable components: 16x6\sqrt{16}\cdot\sqrt{x^6}.

16=4\sqrt{16} = 4 because 42=164^2 = 16.

x6=(x6)1/2=x6/2=x3\sqrt{x^6} = (x^6)^{1/2} = x^{6/2} = x^3.

Step 3: Combine the results.

Combine the simplified components: 4x34x^3.

Therefore, the solution to the problem is 4x3 \boxed{4x^3} .

Answer

4x3 4x^3
