Answer:

-\frac{3p^8}{4q^3}

Step-by-step explanation:

One is given the following expression,

\frac{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.

\frac{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

\frac{3p^-^4q^-^6}{-4p^-^1^2q^-^3}

\frac{3p^-^4^+^(^-^1^)^(^-^1^2^)q^-^6^+^(^-^1^)^(^-^3^)}{-4}

\frac{3p^-^4^+^1^2q^-^6^+^3}{-4}

\frac{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.

\frac{3p^8q^-^3}{-4}

-\frac{3p^8}{4q^3}

_a and .bare complementary angles. Za measures 59"<br> What is the measure of b?
sergeinik [125]

Answer:

Step-by-step explanation:

When two angles add up to 90, they are complementary angles

∠a + ∠b = 90

59 + ∠b = 90

∠b = 90 - 59

∠b = 31°
