I just encountered a problem where I had to take the square root of 600,000. I was trying to figure out how many zeros go after the answer (which I had already approximated), when it dawned on me, I can convert it to scientific notation (with an even exponent) and do it that way.
sqrt(60*10^4) = ~ 7.8*10^2, so ~ 780
Btw, I approximated the sqrt of 60 by knowing that it's between 49 (7*7) and 64 (8*8), but closer to 8. So approximately 7.8
I hope someone finds this helpful.
