Let the number be x Then its square is x^2 3 less than the square of a number is x^2-3 (or x square minus three)
The nonnegative square root of a number?

A square number is any integer multiplied by itself. 2 is even 3 is odd 4 is even and a square of 2 9 is odd and a square of 3 The square of any even number will itself be an even number, and the square of any odd number will itself be an odd number.
Is there any shortcut method to know a number is square or not?
Take LCM of a number and if the LCM denominators fall in pair able group it is a perfect square. for eg: to know the whether 6084 is square number the L.C.M will be 2, 2, 3, 3, 13 & 13 so we have 3 pairs of 2, 3 & 13 therefore 6084 is a square of 2 x 3 x 13 = 78
How do you take the square root of exponents?
You divide the exponent by 2 The square root of a number is that number to the 1/2 power So for examle square root of x cubed (x^3) is x^3 to the half power =x^3/2 (x to the 3/2 power)
Is 3 a perfect square?
No. to be a perfect square, you have to be able to square root it and get a whole number (NOT a decimal) the square root of 3 is 1.732. (1.7322 = 3) a perfect square is a number like 4 the square root of four is 2 (22 = 4)
What is the square root of x if it equals to 3?
square root of x = 3 Since the square root of a number is basically that number to the power of 1/2, if you square both sides it will cancel out the square root.(x1/2)2 = 32x = 32x = 9Since 3 squared is 9, x equals 9.
When you subtract one square number from the other the answer is 3 what are the 2 square numbers?
They are 1 and 4.
A 3-digit number a square number and the product of its digits is 2?
1
Is an irrational number between 2 and 4?
The square root of 3 is an irrational number
Do all square numbers have exactly 3 factors?
No. 81=9*9=3*27=1*81 81 has 5 factors and is a square number. 36=6*6=3*12=1*36=2*18=4*9 36 has 9 factors and is a square number. This doesn't mean that no square numbers have exactly 3 factors though, because: 9=3*3=1*9 9 has 3 factors and is a square number. 4=2*2=1*4 4 has 3 factors and is a square number. All square numbers have an odd number of factors though (because they have a whole number which multiplies by itself to get the number). Factors are whole numbers only, and not decimals. Hope this helps :)
