College Placement Math Exam?
Asked by RyanI am getting ready to take an entrance exam for college mathematics and I am a little stuck on a question that's on the study guide. I just don't know how to approach the exponents under the radical. I don't know how to put a radical sign, so just imagine this entire problem is under a radical. 50x^10y^9z The answer is supposedly 5x^5y4(radical)2yz

sqrt(50x^10y^9z) sqrt(50) = sqrt(25*2) = 5*sqrt(2) sqrt(x^10) = x5 sqrt(y^9) = sqrt(y^8*y) = y^4sqrt(y) so the above becomes, 5x^5y^4*sqrt(2yz)
