A perfect square is the … We start by factoring each radicand, looking for any factors that have a neat whole number as a square root: After factoring each radicand, we can see that there is a perfect square in each: 25 in the first, 49 in the second, and 4 in the third. Rewrite using the Quotient Property. The multiplication of the denominator by its conjugate results in a whole number (okay, a negative, but the point is that there aren't any radicals): Then we look at each factor and determine if any of them has a square root that is an integer. So we can elminate this statement since question is asking ALWAYS true. This is accomplished by multiplying the expression by a fraction having the value 1, in an appropriate form. Whenever you have to simplify a radical expression, the first step you should take is to determine whether the radicand is a perfect power of the index. best Simplifying Multiplying And Dividing Rational Expressions via la-union.org.
