Re: what's the square root of 5
We can linearize the sqrt(x) at x = 4 to get the line y - 2 = 1/4(x - 4)
by plugging in 5 to this line we get y - 2 = 1/4(5-4) which simplifies to y = 1/4 + 2 therefore sqrt(5) is about 2.25, however this is an overestimate since sqrt(x) is concave down for the entire interval for which it is defined. Or just plug it into a calculator and get 2.2360679775... |

sqrt(5) = 2 + 1/(2 + sqrt(5)), hope this helps

That moment when you realize a square root is the same as ^(1/2).

Re: what's the square root of 5
figured out I'm terribly wrong
2.92401774 to the third power is apparently 25 though |
Re: what's the square root of 5
Hmmm looks like you took the cube root of 5 squared then
