# What's the square root of 27?

whats the square root of 27?

1.) There is a special way of figuring any sq. rt. with paper and pencil that I learned in high school that looks like a variation of long division (do the schools even teach that now?)It gives the same answer as ...

2.) Using a calculator for a decimal answer heading toward infinite number of decimal places ...

or break it down into factors, locate any factors that ARE perfect squares, reduce them, and recombine them ... example: sq. rt. of 1800 factors: 100 (perf. sq.) x 9 (perf. sq.) x 2 = 10² x 3² x 2 and the sq. rt of the final equality would be ... 10 x 3 x √2 = 30√2

(read as "thirty onto the square root of two" OR "thirty times the square root of two")

SO √27 wold factor into √9 x √3 = 3√3

*** Note *** I hope that the ascii characters came through. And I'm sure that there are more elegant methods of saying this. It's been a while since I've done this.

The square root of a number is just the number which when multiplied by itself gives the first number. So 2 is the square root of 4 because 2 * 2 = 4.

No number multiplied by itself is going to be 27. Which means that you are going to get a decimal. According to my calculations it would be 5.196152422706632.

the cloest thing is 5.2 which equals 27.04 so it would probably be 5.18 or somethin around there

dependson how your teacher wants it answed then I can help :)

im not sure im horrible at math so far I got a d in math
