Question 50106: I think I got these two but would like to double check before turning in. Thanks!! Andrea
BTW, I apologize in advance for any misunderstanding in my notation as it is hard to do square roots and exponents in the same problem; it is much easier to read with the Math Type program.

(A)
2 sqrt x + 3(x + 1)^2-sqrt(4x) + x^2
2 sqrt x + 3(x^2 + 2x + 1) - sqrt(4x) + x^2
2 sqrt x + 3x^2 + 6x + 3) - sqrt(4x) + x^2
2 sqrt x - 2 sqrt x + 3x^2 + x^2 + 6x + 3
4x^2 + 6x + 3

(B)
sqrt(64x^5) / sqrt(121x^7)
8x^2(sqrt x) / 11x^2(sqrt x^3)

Your answer to part a is correct. With part b, you're on the right track, but it can be simplified even more:
Sqrt(64x^5)/Sqrt(121x^7)
8Sqrt((x^4)x)/11Sqrt((x^6)x)
(8x^2)Sqrt(x)/(11x^3)Sqrt(x)
(8x^2)/(11x^3)
8/(11x)
Good work and good luck in your class!
