Question

rationalize [sqrt(4+x^5)-2]/(x^5) and show me the steps. Whenever I rationalize the numerator it goes to 0, which is bad since I'm trying to find the limit of this function.

Answer 1

so you multiply by sqrt(4+x^5) +2 right

Answer 2

\[\frac{\sqrt{4+x^5}-2}{x^5}\]like that ?

Answer 3

yes satellite

Answer 4

i think you should get a 1 up top, not a zero

Answer 5

you should get --> (4+x^5) - 4 = x^5

Answer 6

riight because the x^5 s cancel to 1, not 0.

Answer 7

Do'oh!

Answer 8

lol how'd i guess?

Answer 9

haha :)

Answer 10

thanks guys.
