What is x squared over x squared?
Since x represents a single number, and it is x squared over x squared, then it will be the same numbers in the numerator and the denominator, no matter what value you replace x with (as long as you replace both x's with the same number). Therefore the answer is 1, unless the value of x is 0, in which case it is undefined. eg: 5 squared / 5 squared = 1 100 squared / 100 squared = 1 Try it with your calculator.
What are 10 complex numbers with the absolute value of 5?
Use the Pythagorean theorem. 5, -5, 5i, and -5i will work, as well as any combination of a real and imaginary number such that (real part) squared + (imaginary part) squared = 25, for example, 4 + 3i, 3 + 4i, 4 - 3i, etc.
What 2 squared numbers equal 1024?
Ah, let's paint a happy little math problem here! To find two squared numbers that equal 1024, we simply need to think of numbers that, when multiplied by themselves, give us 1024. In this case, the numbers are 32 and 32, because 32 squared equals 1024. Isn't that just delightful?
