I'm learning how to simplify radical expressions and I really need help simplifying this one so can someone please help me???(this problem uses a square root box but since I can't put it on here I'll use / so when you see / that means that I'm referring to a square root box)Here's the problem...Simplify the radical expression below...12 / 60x ^2Here's the answer choices...A.) 48x / 15B.) 24 / 15x ^2C.) 48 / 15x ^2D.) 24x / 15Please help me...I'm still learning how to do this.

Sorry for the delay. I've been trying to post my answer all day, but Yahoo! Answers was having technical difficulties.ASSUMPTION: x² is under the radical sign.12√(60x²) =12√(60 * x²)Remember that √(x * y) = √x * √y.12[√60 * √(x²)] =12[√60 * x] =Factor 60.12[√(4 * 15) * x] =Remember that √(x * y) = √x * √y.12(√4 * √15 * x) =12(2 * √15 * x) =12(2x√15) =24x√15ANSWER: D. 24x√15
