Question

Determine the limit of lim x approaches 5 sqrt(8x+5)-sqrt(45)/x-5

Answer 1

\[\frac{(\sqrt{8x+5} - \sqrt{45})(\sqrt{8x + 5} + \sqrt{45}) }{ x-5(\sqrt{8x + 5} + \sqrt{45}) } = \frac{ 8x-40 }{ x-5(\sqrt{8x + 5} + \sqrt{45}) }=\frac{ 8 }{(\sqrt{8x + 5} + \sqrt{45}) }\]

Answer 2

and then take the limitaion

Answer 3

So then I'd get 8/90, should I reduce?

Answer 4

i don't know what the answer is but just reduce yourself..
