Question

Calcule al valor de "a + b + c" si:

72
84
62
78

Answer 1

Explicación paso a paso:

2 = ak

$\frac{2}{k}$ = a

a = bk

$\frac{2}{k}$ = bk

$\frac{2}{k^{2} }$ = b

b = ck

$\frac{2}{k^{2} }$ = ck

$\frac{2}{k^{3} }$ = c

c = 162k

$\frac{2}{k^{3} } = 162k\\2 = 162k^{4}\\\frac{1}{81} = k^{4} \\\frac{1}{3} = k$

a = $\frac{2}{k} = \frac{\frac{2}{1} }{\frac{1}{3} } = 6$

b = 18

c = 54

a + b + c = 78
