The square root of a number is a number that can be multiplied by itself, or 'squared' to get first number.

-2 times -2 is 4

Also, 2 times 2 is 4

Therefore the square roots are 2 and -2

Why is the number i imaginary?

i is equalled to the square root of -1. The square root is a number which, multiplied by itself, will give a number (eg: 2 is the square root of 4 because 2x2=4) But negative numbers can't have square roots because any number multiplied by itself will be positive. So 'i' is imaginary. You use 'i' in calculus to figure out complex problems.

Why does 2 multiplied by root 2 equal to root 8?

When you multiply 2 by √2, you are essentially multiplying 2 by 2^(1/2). Using the properties of exponents, when you multiply two numbers with the same base, you add the exponents. Therefore, 2 * 2^(1/2) = 2^(1) * 2^(1/2) = 2^(1 + 1/2) = 2^(3/2). Simplifying this further, 2^(3/2) is equivalent to √(2^3) = √8.
