please help! is the square of a number greater than the number?
is this not always true? because the square of 0.5 is 0.25 and that is less than the number, but the square of 3 is 9 which is greater than 3.
its sometimes true
only when -1<x>1
thanks
welcome
To determine if the square of a number is greater than the number itself, you need to follow these steps:
1. Choose a number: Let's call it 'x'. The number can be positive, negative, or zero.
2. Calculate the square: Multiply 'x' by itself. This can be done by using the formula: x * x = x^2.
3. Compare the results: Compare the value of 'x^2' to 'x'. If 'x^2' is greater than 'x', then the square of the number is indeed greater than the number itself.
For example, let's take the number '2':
1. Choose a number: x = 2.
2. Calculate the square: 2 * 2 = 4.
3. Compare the results: Since 4 is greater than 2, we can conclude that the square of 2 is indeed greater than 2.
You can repeat this process for different numbers to see if the square is always greater than the number.
