It is important to recall some basic information about powers of numbers. Firstly, a power shows how many times a number is multiplied by itself. For example, if we take the number 2 raised to the power of 2, or squared (written like this: 2^2), we get an answer of 4. This is because 2 x 2 = 4, so we have multiplied 2 by itself twice. Numbers can be raised to any power, even infinity. However, there are some important rules to remember.

Secondly, the reverse operation of powers is roots. Using the same example of 2 being raised to the power of 2, which equals 4, we can take the square root of 4 (√4) and get 2. Note that a number can be raised to any power, and a root can have any coefficient, not just the square root.

Thirdly, numbers raised to powers are known in mathematics as exponentials, and all have exponential function graphs, either exponential growth or exponential decay. Thus, we need to recall some basic rules:

  • Any number raised to the power of 0 equals 1.
  • If a number is raised to a negative power, it can be rewritten as 1 divided by that number raised to the power, e.g., 2^-2 = 1/2^2.
  • If a number is raised to a power expressed as a fraction, it should be rooted, e.g., 4^1/2 = √4 = 2.
