Provide an appropriate response.Tell whether the statement is true or false. If it is false, give the correct answer. Explain your answer. The easiest way to simplify the expression 
is to multiply both the numerator and denominator by 10 - 
What will be an ideal response?
True. Multiply numerator and denominator by the conjugate of the denominator, 10 - 
, so that, by using the product of the sum and difference of two numbers, the "middle term" of the product is zero.
