2. Negative Integer Exponent Rule

Answer 1

When dealing with negative integer exponents, the following rule applies:
a^(-n) = 1/a^n

This means that if a number is raised to a negative exponent, you can rewrite it as the reciprocal of the same number raised to the positive exponent. For example:
2^(-3) = 1/2^3 = 1/8

This rule helps simplify calculations involving negative exponents and can be applied to any base number.
