Which expression is equivalent to quantity y raised to the negative third power times z raised to the fifth power end quantity over quantity z raised to the negative fourth power times y raised to the sixth power end quantity all raised to the negative second power?

Sagot :

Using exponent properties, the equivalent expression is:

[tex]\frac{y^{18}}{z^{18}}[/tex]

What is the equivalent expression?

The original expression is:

[tex]\left[\frac{y^{-3}z^5}{z^{-4}y^6}\right]^{-2}[/tex]

When two terms that are divided have the same base and different exponents, we keep the base and subtract the exponents, hence:

[tex]\left[\frac{y^{-3}z^5}{z^{-4}y^6}\right]^{-2} = [y^{-3 - 6}z^{5 - (-4)}]^{-2} = [y^{-9}z^9]^{-2}[/tex]

The negative exponent at the numerator goes to the denominator, hence:

[tex][y^{-9}z^9]^{-2} = \left[\frac{z^9}{y^9}\right]^{-2}[/tex]

The negative outer exponent means that we have to exchange the numerator and denominator, hence:

[tex]\left[\frac{z^9}{y^9}\right]^{-2} = \left[\frac{y^9}{z^9}\right]^{2}[/tex]

Then both numerator and denominator exponents multiply by 2, hence the equivalent expression is:

[tex]\frac{y^{18}}{z^{18}}[/tex]
