Question

whats the lim x goes to infinity of 2/square root of x

Answer 1

0

Answer 2

yes

Answer 3

Rose if you're not convinced, just plug a large number into your calculator to check! :)
if you plug one bajillion in for x, what value do you get for the limit?

\[\frac{ 2 }{ \sqrt{bajillion} }\approx \frac{ 2 }{ 999999999 } \approx 0\]

Answer 4

yeah, but do what zepdrix said only for check, because if you do this in a test for example, it will be wrong because infinity is NOT a number...

Answer 5

okay

Answer 6

it is always 0 ?

Answer 7

no! it will depends on what you are taking the limit, always try to simplify the limit, try to do not have a denominator, in this case we can not simplify so we do this

Answer 8

i am trying to solve this problem where x goes to infinity 2+square root of x/ 2- square root of x

Answer 9

i am getting the answer as 1, is it right?

Answer 10

\[\lim_{x \rightarrow \infty}\frac{2+\sqrt{x}}{2-\sqrt{x}}\]

Answer 11

this one?

Answer 12

yes,

Answer 13

the limit is equal to -1

Answer 14

have you already study L'hospital rule ?

Answer 15

can you please explain how you got -1?

Answer 16

No,

Answer 17

ok let me explain
