      well, to the power means the number, times itself, however many times the power is. for example,
      2 to the fourth power would be 16. because 2 times two is four, that times two is eight, eight times two is sixteen. 2*2*2*2. so five to the three would be 5*5*5. I bet you can find the answer from there.

      Yes, we can use in imaginary numbers, where (-1)²=i , I think you're gonna see it at the pre-cauculus subject.

      Squaring numbers (article) | Khan Academy (26)

      Good question! In the real number system, it is not possible to find the square root of a negative number, since no real number times itself is negative. This is because 0 times itself is 0, a negative number times itself is positive, and a positive number times itself is positive.

      To get around this problem, mathematicians invented the imaginary unit i, defined as the square root of -1. This produces an extended number system called the complex numbers, defined as numbers in the form a+bi where a and b are real numbers. For example, 8, 3 - 2i, and 5i are complex numbers. Also, 5i is an example of what is called a pure imaginary number, because 5i is just a real number times i.

      Have a blessed, wonderful day!

      I guess socially, stick to your own friend groups and stay out of trouble, but academically, ask as many questions as you can so you can get a firm understanding of what you're learning.

      Yes, just the opposite process!
      You can say that "squaring" and "square rooting" are inverse operations. (when n >= 0 though)

      It means it's repeating over and over, it comes in handy when you have a 'repeating decimal'. You'll probably learn about repeating decimals when you start to learn about shifting fractions into decimals. Hope that helps <3
