4-
${2}^{ - 3} . {2}^{5} =$

Answer 1

1) $2^{3} *2.2^{5}$

$8*2.2^{5}$

$8*(\frac{11}{5})^{5}$

$8*\frac{11^{5} }{5^{5} }$

$\frac{8*11^{5} }{5^{2} }$

$\frac{8*11^{5} }{3125}$

$S=\frac{8*11^{5} }{3125}$

2) $(-3)^{3} *(- 3)^{2}$

$(-3)^{3+2}$

$(-3)^{5}$

$-243$

$S=-243$

3) $4^{4} * 4^{4}$

$4^{4+4}$

$4^{8}$

$S=4^{8}$

4) $2^{-3} * 2^{5}$

$2^{2}$

$4$

$S=4$

Answer 2

Explicação passo-a-passo:

$1 -$

$2 {}^{3} .2.2 {}^{5} = 2 {}^{3 + 1 + 5} = 2 {}^{9}$=

$2)$

$( - 3) {}^{2} .( - 3) {}^{2} = ( - 3) {}^{2 + 2} = ( - 3) {}^{4}$

$3)4 {}^{4} .4 {}^{4} = 4 {}^{4 + 4} = 4 {}^{8}$

4) $2 {}^{ - 3} .2 {}^{5} = 2 {}^{ - 3 + 5} = 2 {}^{2}$
