lim sqrt [(2+3x)/(1-5x)]

x--->infinity

I got no idea with how to do this one. Can anyone please teach me how to do it?????THANKS A LOT!!!

As x-> infinity, the ratio inside the brackets becomes -3/5, because the constant terms (2 and 1) become negligible. The square root of -3/5 is an imaginary number, 0.774597i
