Solution

Simplify by removing factors from the radicand.

  3xy2 .

Given:

The given expression is 27x3y63 .

Concept Used:

  • Find the largest factor in the radicand that is a perfect power of the index. Rewrite the radicand as a product of two factors, using that factor.
  • Use the product rule to rewrite the radical as the product of two radicals.
  • Simplify the root of the perfect power.

Calculation:

The given expression is 27x3y63 .

Let a=27x3y63

   a= (27 x 3 y 6 ) 1/3 a=(3)(3)(3)x3y3y31/3a=(3)3x3y3y31/3a=3xyya=3xy2

Thus the solution of given expression 27x3y63 is 3xy2 .
