It used to be taught many years ago but he advent of calculators and computers have essentially eliminated that. It is a good discipline to learn in school, however, so would be nice to be brought back, but unlike say, long division, it is a bit more complicated.
It is taught at the appropriate stage.

sqrt(0.0004) = +/- 0.02. Try calculating (+0.02)^2 and (-0.02)^2 by hand to convince yourself that both are real roots of 0.0004. ================
For calculating simple fractions, i.e. that are only numbers and that do not include square roots in them, However, if you are going to use square roots, pi, sin, cos, tan and etc. The choice of calculator to use depends on how complex the fractions you are putting in are.
The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07The square roots are -1.07 and +1.07
square inches do not have square roots only number have square roots.
Perfect square roots are square roots that have a whole number that can go into it perfectly. Nonperfect square roots are square roots that have decimal numbers going into it. Example: Perfect Square Root: 144- Square Root: 12 Nonperfect Square Root: 24- Square Root: About 4.89
No. The square roots 8 are irrational, as are the square roots of most even numbers.
The square roots of 64 are +8 and -8.
You call them principal square roots.
The square roots of 8100 are 90, -90
The answer depends on "different from WHAT?" Positive cube roots, or negative square roots?
