Question

COPIE OS ITENS SUBSISTINDO CADA *QUADRADO* PELO SÍMBOLO >,< OU =

Answer 1

Resposta:

Explicação passo-a-passo:

A) =

$12^{8}$×$5^{8}$ =

(12x5)$x^{8}$=

$60^{8}$

b) <

$7^{3} + 4^{3} =$

343 + 64 =

407

$(7+4)^{3} =\\11^{3}\\ 1331$

c) =

(6 ÷ 5)$^{9}$ = $\frac{6^{9} }{5^{9} }$

d) >

$(5^{3}-2^{3} =$

125 - 8

117

(5-2)$^{3}$

$3^{3}$

3.3.3= 27

E) <

$10^{-2} =\\\frac{1}{10^{2} } =\\\frac{1}{100} ou 0,01$

$2^{-2} + 6^{-2}\\2^{-2}(2^{-2}+3^{-2}) = 0,09...$

F) >

$6^{3}-4^{3}=\\  (3x2)^{3}-2^{6}=\\3^{3}x2^{3}-2^{6}=\\    (3^{3}-2^{3})x2^{3}\\   (27x8)x8\\19x8=\\152$

$2^{3}=\\2x2x2=8$
