Simplfy a number raised to a negative power
WebbThe rule states that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power. In other words, an expression raised to a negative exponent is equal to 1 divided by the expression with the sign of the exponent changed. Hence, for any non – zero real number ‘ a ‘ and a positive integer n, we define. WebbTo solve expressions involving negative exponents, first convert them into positive exponents using one of the following rules and simplify: a -n = 1/a n 1/a -n = a n Example: Solve: (7 3) × (3 -4 /21 -2) Solution: First, we convert all the negative exponents to positive exponents and then simplify. Given: 73×3−4 21−2 7 3 × 3 − 4 21 − 2

WebbFor the power rule, with n = 2 n = 2 and m = \frac {1} {2} m = 21, the LHS is \big (a^2\big) ^ { \frac {1} {2} } = a (a2)21 = ∣a∣, while the RHS is a^ { 2 \times \frac {1} {2} } = a a2×21 = a. These are not equal. There are also special cases to consider when dealing with negative or complex values. WebbWell, if the original exponent is not a multiple of 4 4, then finding the closest multiple of 4 4 less than it allows us to simplify the power down to i i, i^2 i2, or i^3 i3 just by using the fact that i^4=1 i4 = 1.

WebbMultiplying negative exponents For exponents with the same base, we can add the exponents: a -n ⋅ a -m = a -(n+m) = 1 / a n+m Example: 2 -3 ⋅ 2 -4 = 2 - (3+4) = 2 -7 = 1 / 2 7 …
