Answer 1

Explanation:

Answer 2

`-(3p^8)/(4q^3)`

Explanation:

One is given the following expression,

`(15p^-^4q^-^6)/(-20p^-^1^2q^-^3)`

Since (15) and (-20) are both divisible by (5), one can divide both terms by (5) to simplify it.

`(3p^-^4q^-^6)/(-4p^-^1^2q^-^3)`

Now bring all of the terms with a negative exponent to the numerator. Multiply the exponents by (-1), then add them to the exponents of the like term in the numerator. Simplify the resulting exponents

`(3p^-^4q^-^6)/(-4p^-^1^2q^-^3)`

`(3p^-^4^+^(^-^1^)^(^-^1^2^)q^-^6^+^(^-^1^)^(^-^3^))/(-4)`

`(3p^-^4^+^1^2q^-^6^+^3)/(-4)`

`(3p^8q^-^3)/(-4)`

Rewrite the fraction such that there are no negative exponents. Remember the rule, when bringing a number from the numerator to the denominator and back, multiply the exponent of the number by (-1). One can only switch numbers between the numerator and the denominator when all operations are multiplication or division.

`(3p^8q^-^3)/(-4)`

`-(3p^8)/(4q^3)`
