whats the square root of 27?

Answer #1

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.

Answer #2

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.
