Exponents

This topic introduces the laws of exponents, particularly integer exponents and rational exponents.

An exponent tells us how many times a base is multiplied by itself. For example, $3^4=3\times3\times3\times3$ .

If the base is negative, brackets matter. For example:

$(-2)^3=-8$
$(-2)^4=16$
$-2^4=-16$ because the exponent acts on the $2$ first, then the negative sign is applied.
