Index of some Chinese and English words

If A and B represent two algebraic expressions and B contains letters, then the formula A/B is called a fraction.

The numerator of a fraction is multiplied by the denominator or divided by an algebraic expression that is not equal to 0, and the value of the fraction remains the same.

Law of fractional multiplication: fractional multiplication, the product of molecules is the numerator of the product, and the product of denominator is the denominator.

Law of fractional division: a fraction is divided by a fraction, and the numerator and denominator of the divisor are in turn multiplied by the divisor.

Fractional power should be numerator and denominator respectively.

a^-n= 1/a^n (a? 0) that is to say, a-n (a? 0) is the reciprocal of n.
