Question

Calcule:$\left[\begin{array}{ccc}\\(8\frac{1}{2})^{4} \\.\end{array}\right]$+16$\frac{1}{4}$-27$\frac{2}{3}$
por favor!
com explicação se possivel pq eu não sei!

Answer 1

$\left[\begin{array}{ccc}\\(8\frac{1}{2})^{4} \\.\end{array}\right]+16.\frac{1}{4}-27.\frac{2}{3}$

Vamos converter da forma mista para imprópria

$8 \frac{1}{2} = \frac{8 \times 2 + 1}{2} = \frac{17}{2}$

$16\dfrac{1}{4}=\dfrac{65}{4}$

$27\dfrac{2}{3}=\dfrac{83}{3}$

${( \frac{17}{2} )}^{4}+\dfrac{65}{4}-\dfrac{83}{3} \\ =\frac{83521}{16}+\dfrac{65}{4}-\dfrac{83}{3}= \frac{250563+780-1328}{48} \\=\frac{250015}{48}$
