CAN SOMEBODY PLEASE HELP ME WITH A CALCULATOR AND TELL ME WHAT 27^(-1/2) IS? THAT READS "27 TO THE NEGATIVE ONE HALF". THANK U! enter 27 press the y^x or x^y key, whichever you have enter (1/2 +/- ) press = to get .19245

**math**

what is 27^(-1/2)? thanks. i don't have my calculator on me. well, that's the same as 1/(square root of 27).. so if you simplify it, you will end up with 1/(3square root of 3).

Okay, how would you go about finding the area of a curve from 1 to 4, when y=2x+(2/(x^2))?? It's not like the problem I asked before because here, you cannot use substitution. I tried using 2x for u and x^2 for du but it won't simplify into a ln problem or anything ...

How do you integrate using substitution: the integral from 1 to 3 of: ((3x^2)+(2))/((x^3)+(2x)) There is a trick to this one that grealy simplifies the integral. Let u = x^3 + 2x. Then du = (3x^2 + 2)dx The integral then bemoces just the integral of du/u, which is ln u = ln (x...
