Question

Atividade 3 _ Determine o valor das expressões dadas, apresentando o resultado em notação científica.

Answer 1

Explicação passo-a-passo:

a) $A=\dfrac{9,6225\cdot10^6}{1,5\cdot10^{-5}}$

$A=6,415\cdot10^{6+5}$

$A=6,415\cdot10^{11}$

b) $B=\dfrac{8,25\cdot10^6}{5\cdot10^3}$

$B=1,65\cdot10^{6-3}$

$B=1,65\cdot10^3$

c) $C=3,2\cdot10^3\times1,6\cdot10^{-2}$

$C=5,12\cdot10^{3-2}$

$C=5,12\cdot10^{1}$

d) $D=0,5\cdot10^{-5}\times5,2\cdot10^{23}$

$D=2,6\cdot10^{-5+23}$

$D=2,6\cdot10^{18}$
