Work out b(4½-3⅔)+1⅔

Zolol [24]

Answer:

2 $\frac{1}{2}$

Step-by-step explanation:

Change the mixed numbers to improper fractions

( $\frac{9}{2}$ - $\frac{11}{3}$ ) + $\frac{5}{3}$ ← the LCM of 2 and 3 is 6

= $\frac{9(3)}{2(3)}$ - $\frac{11(2)}{3(2)}$ + $\frac{5(2)}{3(2)}$

= $\frac{27}{6}$ - $\frac{22}{6}$ + $\frac{10}{6}$

= $\frac{5}{6}$ + $\frac{10}{6}$

= $\frac{15}{6}$

= $\frac{5}{2}$

= 2 $\frac{1}{2}$

A ^-4 / a ^-6 please simplify and show your work if possible <:D

kipiarov [429]

$\bf ~\hspace{7em}\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} ~\hspace{4.5em} a^n\implies \cfrac{1}{a^{-n}} ~\hspace{4.5em} \cfrac{a^n}{a^m}\implies a^na^{-m}\implies a^{n-m} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{a^{-4}}{a^{-6}}\implies a^{-4}\cdot a^6\implies a^{-4+6}\implies a^2$
