rational expressions!



If i see this on a math test, my first reaction would be "WOAH! o.o how am i suppose to do this?!" But after breaking it down, and realizing that it is just many smaller steps mashed into one equation, i realize it isnt very hard to solve ^^

For the first equation:
1) you always want to get rid of the negative exponents first, so you first switch the numbers with the negative exponents to the top or bottom, turning it to be positive.
2)next you take the 5/2 and put it with each of the digits.
3)solve each of the mini math question that has the 5/2 now.
3) than make sure your final number is in the simplest form! voila! you're done ^^

For the 2nd equation:
1) first you want to take out the first root.
2) solve the new equations, and than take out the second root.
3) than solve the equation
4) make sure it is in simplest form! You're done! ^^

(i did not have the newest version of word so i coulnd't showed step by step with the answers)
