Exponentiation is one of the fundamental operations in math.
It involves raising numbers to powers.
For example, in the expression \(a^n\), \(a\) is the base and \(n\) is the exponent.
The exponent tells us how many times to multiply the base by itself.
So, \(2^3 \) means \(2\) multiplied by itself three times, which equals \(8\).
This operation helps us to handle very large numbers and very small numbers easily, especially in scientific notation.
When dealing with negative exponents, like \(a^{-n} \), it signals that we should take the reciprocal of the base raised to the positive exponent.
For instance, \(2^{-3} = \frac{1}{2^3} = \frac{1}{8}\). So, remember: positive exponents multiply, and negative exponents take the reciprocal.
This makes working with algebraic expressions containing exponents much smoother!

Inverse properties are crucial in understanding negative exponents.
Basically, these properties tell us how to
