Answer :
To find the square root of a number, you should probably use a calculator.
1) Type 476 into your calculator
2) press the √ button
*some calculators are different, so to do this just do step 2 first then 1
your answer will come out to be: 21.82 or just 21.8 (keep in mind that i'm rounding)
21.817 how would you find this? The square root means when 2 numbers are the same and they times each other then it makes another number. There are perfect squares, rational, and non rational.
So 21.81 x 21.81 should be about 476 since we rounded
So 21.81 x 21.81 should be about 476 since we rounded
