Question 327569: I need help with two problems, if you can help me.
1. Perform the indicated operations & simplify
v-3 over v-5(fraction)- v+1 over v+5 (fraction) + v-25 over v^2-25 (fraction).
2. use rational exponents to write x 1over6(fraction)* y1over4 (faction) * z1over7 (fraction) as a single radical expression.
