Question

calcule 2,4*10^-6*5*10^-5=

Answer 1

$[(2,4)*10^{-6}]*[(5)*10^{-5}]$

Simplificamos o expoente negativo

$[(2,4)*\dfrac{1}{10^{6}}]*[(5)*\dfrac{1}{10^{5}}]$

Potencialize as bases

$[(2,4)*\dfrac{1}{1000000}][(5)*\dfrac{1}{100000}]$

Agora, multiplique os valores para as frações

$[\dfrac{2,4}{1000000}]*[\dfrac{5}{100000}]$

Reduza os valores

$[0,0000024]*[0,00005]$

Multiplique os valores

0,0000000001

Resposta:
$\boxed{S = 0,0000000001}$
