Nikki 16 student, senior 3) squareroot of x^{2} + 10x + 25 4) sixthroot of (m + 4)^{6} 5) cuberoot of 64r^{6}w^{15} 6) squareroot of 49m^{2}t^{8} 13) cuberoot of (2x + 1)^{3} 14) fifthroot of 32x^{5}y^{10} 15)  squareroot of 144m^{8}n^{6} 16) cuberoot of 49a^{10}b^{16} 17) fifthroot of 243x^{10} 18)  squareroot of 49a^{10}b^{16} 19) fourthroot of (x  5)^{8} 20) cuberoot of 343d^{6} I really need to know if I have the right answers for these could you please tell me how they are done and what you come up with. Thanks. Hi Nikki,
3) First factor it and you should see something like problem 13). = (2)^{5}x^{5}(y^{2})^{5} = [2xy^{2}]^{5} Penny
