Estimate, then narrow the range. For example, if you want to find the sqrt of 13, you know it's between 3 and 4. Try 3.5 - it's too low, so now try halfway between 3.5 and 4, 3.75 - it's too high. Now try a number between 3.5 and 3.75, say 3.6. It's just a bit low, so try 3.61, which is a bit high. Continue until your result is as close to 13 as you want.
It's better to get a scientific calculator if you need to do math like this.
Scientific calculators have a square key which is usually marked x2. The same key, preceded by the "shift" key will give the square root.
the z looking thing
Assuming the calculator can do exponents, take the number and raise it to the power of 1/2.
try to find what number times the same numbers equals the number that you have.
D. enter the number; press the square root key
Enter the number you wish to find the square root of, and then raise it to the power of one-half. x^0.5 = sqrt(x)
With great difficultly because it is an irrational number and it is about 14.69693846 by using a calculator
It depends on the calculator - some have the sqrt function, with others you need to use the exponent.
using calculator , it will be equal to11.44
use a calculator
Use a calculator (if you need) to find the principal square root. The second square root is the negative of the number.
If your calculator has an exponentiation function, simply raise the number to the power of .5 Remember this trick: the nth root of X = X ^ (1/n)
The square root button on a calculator is normally the button which resembles a 'tick' symbol. Depending on the calculator you will press this before or after entering the number you wish to square root.
