You need to find the two nearest perfect squares roots that are close to n.
Divide the given number by one of those numbers. Take the average of the number produced and the root. Check if we square this average, results in the original number or not. If you do not get an answer then repeat the steps. Hope this helped!
u cant get the excat answer but if you want 1) To find imperfect squares you estimate the square to the nearest integer 85 2) This is an imperfect square because no whole number multiplies itself to equal 85 you find the closest square but less than the imperfect squares answer 9*9=81 4) Now you find a square that is closest higher than the imperfect squares answer 10*10=100 5) So 85 lays between 9 and 10
count the top row of squares and multiply that by the number of squares in a coloumn ( which are going down )
In the classic puzzle with squares of differeing sizes within squares, the number is 40.Its a popular net puzzle.
Find the perfect squares that your number lies between. Your square root will lie between their square roots. Whichever it is closer to will indicate the size of the decimal.
count the number of squares, then times by the area of each square A=1/2(base*height) can also be used
You square each number and multiply that by the frequency with which that number appears. You then sum together these results.
102 + 32 = 100 + 9 =109 (not an even number)
There is no simple way to find square roots in your head. You may be able to do it for a small number of perfect squares but that is about it.
There is no real way to find a square root of any number mentally. The best way to estimate is to think of easy squares near the number. 312 = 961, and 322 = 1024, so the square root of 983 has to be between those two. Using a calculator, we can find that it's 31.35

You need to know (or be able to find) perfect squares. Suppose you want to find two numbers that the square root of 27 is between. You need to find a number, N, such that N2 < 27 but the square of the next number is bigger ie (N + 1)2 > 27 The nearest perfect squares, on either side of 27 are 25 and 36. That is, 25 < 27 < 36 Taking square roots, 5 < sqrt(27) < 6 However, it is also true that -6 < sqrt(27) < -5
The square of the number of tiles on each row or column. Generally a chess board has 64 squares. This answer given above by one of our friends is true only incase of squares of same size. But as we consider all possible squares of different sizes, then it will be calcualted using the formula, 12+22+32+42+52+62+72+82
