Question

Which two consecutive integers does - -V138 lie between?А)11 and 12B)12 and 13C)-11 and -12D)-12 and -13

Answer 1

We have to find between which integers is located in the square root of 138.

If we calculate 11^2 we have 121.

As 121 < 138, the square root of 138 is then bigger than 11.

If we calculate 12^2, we have 144.

As 144 > 138, the square root of 138 is smaller than 12.

So, the square root of 138 has to be between 11 and 12.
