Negative Exponent Reciprocal of Positive Exponent Answer; 4-2 = 1 / 4 2 = 1/16 = 0.0625: Det motsatta gäller om exponenten är negativ: då blir potensen mindre när basen blir större. Exempel 10 \displaystyle \quad 5^{3/2} > 4^{3/2}\quad eftersom basen \displaystyle 5 är större än basen \displaystyle 4 och båda potenserna har samma positiva exponenten \displaystyle 3/2 . Ellyix skrev: Genom att ta upp den negativa exponenten till 1 och sedan dividera det med basen får du fram svaret.
If it’s on the numerator, put it to the denominator and make the exponent positive. If it’s on the denominator, put it to the numerator and make the exponent positive. Keep in mind that the negative exponent does not affect the sign of the answer.
For instance, " x –2 " (pronounced as "ecks to the minus two") just means " x 2 , but underneath, as in 1/( x 2 ) ". So wherever the term with a negative exponent is written, put it to the opposite location. If it’s on the numerator, put it to the denominator and make the exponent positive.
