Question

O valor de :
${2 }^{ - 3} + {3}^{ - 1} \div {2}^{0} + {2}^{ 1} + { \binom{1}{2} }^{ - 3}$
a)1
b)24
c)1/24
d)8
e)1/8

Answer 1

${2 }^{ - 3} + {3}^{ - 1} \div {2}^{0} + {2}^{ 1} + { \binom{1}{2} }^{ - 3}$
${ \frac{1}{2} }^{ 3} + { \frac{1}{3} }^{ 1} \div {2}^{0} + {2}^{ 1} + { 2}^{ 3}$
$\frac{1}{8} + \frac{1}{3} \div 1 + 2 + 8$

11/24 / 11/1

=1/24
