Video Solution

Solution Steps

00:00 Find the value X
00:03 Isolate X
00:12 Breakdown 36 into factors of 6 and 6
00:19 When multiplying the root of a number (A) by the root of another number (B)
00:22 The result equals the root of their product (A times B)
00:25 Apply this formula to our exercise, and convert one root to 2
00:30 Simplify wherever possible
00:34 This is the solution

Step-by-Step Solution

To solve the equation 6x=36 \sqrt{6}x = \sqrt{36} , we will proceed with the following steps:

  • Step 1: Simplify the square root on the right-hand side.
    36=6\sqrt{36} = 6.
  • Step 2: Substitute the simplified value back into the equation to obtain:
    6x=6\sqrt{6}x = 6.
  • Step 3: Solve for x x by isolating the variable. Divide both sides by 6\sqrt{6}:
    x=66 x = \frac{6}{\sqrt{6}} .
  • Step 4: Simplify the fraction:
    Multiply the numerator and denominator by 6\sqrt{6}:
    x=6×66×6=666=6 x = \frac{6 \times \sqrt{6}}{\sqrt{6} \times \sqrt{6}} = \frac{6 \sqrt{6}}{6} = \sqrt{6} .

Therefore, the solution to the equation is x=6 x = \sqrt{6} .

Answer

6 \sqrt{6}
