Por favor me ajudem, é para segunda feira, ficaria agradecida, Beijos❤

Answer 1

Resposta:

E)6,89

F)5,5

G)$\frac{11}{12}$

H)12

I)3

J)$8^{\frac{1}{2} }$

L)2

M)-0,5

Explicação passo-a-passo:

E)3,25.2,12=$6,89$

Cálculo:

$\frac{13}{4} .\frac{53}{25}\\\\\frac{689}{100} \\\\6,89$

F)$\frac{5}{2} +3=$$5,5$

Cálculo:

$\frac{5}{2}+3\\ \\2,5+3\\\\5,5$

G)$\frac{2}{3} -\frac{1}{4}+\frac{1}{2} =$$\frac{11}{12}$

Cálculo:

$\frac{2}{3}-\frac{1}{4} +\frac{1}{2} \\\\\frac{11}{12}$

H)$2^{0} +2^{1}+3^{2} =12$

Cálculo:

$2^{0} +2^{1} +3^{2} \\\\1+2+9\\\\12$

I)$\sqrt{25} -4^{\frac{1}{2} } =$$3$

Cálculo:

$\sqrt{25} -4^{\frac{1}{2} } \\\\5-\sqrt{4} \\\\5-2\\\\3$

J)$\sqrt{\sqrt{64} } =8^{\frac{1}{2} }$

Cálculo:

$\sqrt{\sqrt{64} } \\\\\sqrt{8} \\\\8^{ \frac{1}{2} }$

L)$2521^{0} +1^{1231} =2$

Cálculo:

$2521^{0} +1^{1231}\\\\1+1\\\\2$

M)$\frac{3}{2}-\frac{10}{5}=-0,5$

Cálculo:

$\frac{3}{2}-\frac{10}{5} \\\\1,5-2\\\\-0,5$

Espero ter ajudado :-)
