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.
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
To find the square root on a calculator without a radical symbol, you can use the power function. Simply raise the number to the power of 0.5 to find the square root. For example, to find the square root of 16, you can input 16^0.5 into your calculator to get the result.
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)
Press the square root button on your calculator.
It is somewhere between 3 and 4. You can get a better approximation by using your calculator to get the square root of 11.
