\bf ~~~~~~~~~~~~\textit{negative exponents}\\\\&#10;a^{-n} \implies \cfrac{1}{a^n}&#10;\qquad \qquad&#10;\cfrac{1}{a^n}\implies a^{-n}&#10;\qquad \qquad &#10;a^n\implies \cfrac{1}{a^{-n}}\\\\&#10;-------------------------------\\\\

\bf (4x^{-2}y^3 \div xy^{-4})^{-2}\implies \left( \cfrac{4x^{-2}y^3}{xy^{-4}} \right)^{-2}\implies \left( \cfrac{xy^{-4}}{4x^{-2}y^3} \right)^{2}&#10;\\\\\\&#10;\textit{then we distribute  the exponent}\left( \cfrac{x^2y^{-4\cdot 2}}{4^2x^{-2\cdot 2}y^{3\cdot 2}} \right)\implies \cfrac{x^2y^{-8}}{16x^{-4}y^6}&#10;\\\\\\&#10;\cfrac{x^2\cdot x^4}{16y^6\cdot y^8}\implies \cfrac{x^{2+4}}{16y^{6+8}}\implies \cfrac{x^6}{16y^{14}}

You work with 3 other students on a project for science class. Your group
aleksandrvk [35]

Answer:

350 points are possible

Step-by-step explanation:

You take 329 divided by 94% or .94 to get 350.

100% of 350 is 350

To double check, 94% of 350 is 329 & 6% of 350 is 21.  329 +21 = 350
