Question

gente ajuda por favor ​

Answer 1

a)

${2}^{3} = 2 \times 2 \times 2 = 8 \\ {2}^{2} = 2 \times 2 = 4 \\ {2}^{1} = 2 \\ {2}^{0} = 1 \\ {2}^{ - 1} = ( { \frac{1}{2} })^{1} = \frac{1}{2} \\ {2}^{ - 2} = ( { \frac{1}{2} })^{2} = \frac{1}{4} \\ {2}^{ - 3} = ( { \frac{1}{2} })^{3} = \frac{1}{8}$

b)

${3}^{3} = 3 \times 3 \times 3 = 27 \\ {3}^{2} = 3 \times 3 = 9 \\ {3}^{1} = 3 \\ {3}^{0} = 1 \\ {3}^{ - 1} = ( { \frac{1}{3} })^{1} = \frac{1}{3} \\ {3}^{ - 2} = ( { \frac{1}{3} })^{2} = \frac{1}{9} \\ {3}^{ - 3} = ( { \frac{1}{3} })^{3} = \frac{1}{27}$
