WebNegative exponents: Relate the unknown (negative exponent) to the known (positive or zero) using our formula: x-1 x¹ = x⁰ so x-1 x = 1 Solving for x-1 shows x-1 = 1/x Powers of powers: (x a)3 = x a x a x a = x a+a+a = x 3a. Fraction powers: x 1/2. How can we relate it to what we know? We want whole numbers so x 1/2 x 1/2 = x¹= x WebMathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields.

Fractional Derivatives. And How to Calculate Them - Medium
WebRecall that negative exponents indicates that we need to move the base to the other side of the fraction line. For example: x^ {-4} = \dfrac {1x^ {-4}} {1} = \dfrac {1} {x^4} x−4 = 11x−4 = x41 \dfrac {1} {x^ {-3}} = \dfrac {1} {1x^ {-3}} = \dfrac {1x^3} {1} = … WebJan 31, 2024 · The negative in the exponent makes it a fraction and the $1/2$ just makes it a regular square root .
