36 is the square of 6; 100 is the square of 10; 121 is the square of 11. 71, 62, and 343 are not squares of whole numbers.
There is a trick to this one. cube the first and write it down. write the opposite sign of the middle term. multiply the first constant times the second constant times 2 and write it down. square the first term write it down, square the second term and write it down. cube the last term including its sign and write it down. Example: (a-b)^3= a^3+2a^2b^2-b^3 (2x+3y)^3=8x^3=12x^2y^2+27y^3
-- Write down a list of the first ten whole numbers. -- For each one, multiply it by itself, and write the product next to it.
2, 3, 5, 7, 11, 13
Then you write down both numbers

Then you write down both numbers
-- Write down the number of kwh -- Write down the number of square feet -- Divide the first number by the second number. -- The answer is mathematically correct, but doesn't appear to have any physical significance in the real world.
- Start counting, from ' 1 '. - Each time you say a number, think about its square ... the number you said, multiplied by itself. - If the square is less than 200, write it down. - If the square is more than 200, stop. The job is done. You should have 14 numbers on your list.
There are infact two numbers which go with this problem they are:23 and 24.When you square 23 you get 529 and when you square 24 you get 576.I hope so it will provide some help............
There are 31 of them. You can find them easily on your own, like this:-- On a piece of paper, write the numbers from 1 to 31 in a vertical column ...down the side of the paper.-- Start with ' 1 '. Multiply each number by itself, and write the result next to it.-- Next to 1, you'll write '1'. Next to '2', you'll write '4'. Next to '3', you'll write '9'.Keep going like that, one at a time, all the way down your list of numbers.-- When you get down to 31, you'll write '961' next to it, and that'll be the biggestperfect square number that's less than 1,000 . The next one is 1,024.
That's one way to do it. The problem with that method is that you're usually wrong. A much more reliable method is to figure it out with arithmetic. All you have to do is . . . -- Write the number down. -- Write it down again. -- Multiply the two numbers you see written down. If you multiply correctly, then the answer you get this way is always the correct square of the number.
