Question

Can you help in solving

Answer 1

Explanation:

• To raise a fraction to a power raise the nominator and denominator to that power write all nominator above the common denominator. use
• 
  `{(x - y) ^(2) } = {x }^(2) - 2xy + {y}^(2)`
• collect like terms. To take a root of fraction take the root of nominator and denominator sperate. use the commutative property use
• 
  `{x}^(2) + 2xy + {y }^(2) = {(x + y)}^(2)`
• to reduce the index of the radical and exponent with 2
