WebBut the problem in the video is 125^(1/2)/5^(1/2). These are not the same number. So, you need to use properties of exponents to convert to a common base. Or, as Sal shows in the video, we can rewrite the problem has one fraction raised to the common exponent. This then lets him reduce the fraction. Hope this helps. Websimplifying first: \left (-3x^ {-1}y^2\right)^2 (−3x−1y2)2 = \left (\dfrac {-3y^2} {x}\right)^2 = ( x−3y2)2 = \dfrac { (-3)^2 (y^2)^2} { (x)^2} = (x)2(−3)2(y2)2 = \dfrac {9 y^4} {x^2} = x29y4 squaring first: \left (-3x^ {-1}y^2\right)^2 (−3x−1y2)2 = (-3)^2 (x^ {-1})^2 (y^2)^2 = (−3)2(x−1)2(y2)2 = (9) (x^ {-2}) (y^4) = (9)(x−2)(y4) WebDec 5, 2024 · To simplify algebraic fractions, start by factoring out as many numbers as you can for the numerator, which is the top part of the fraction.
