Question

5.10 elevado a menos 7​

Answer 1

Resposta: 0,0000005

$5*10^{-7}=?\\\\5*105*10^{2}=5*100=500,0\\5*10^{1}=5*10=50,0\\5*10^{0}=5*1=5,0$

Conforme diminui-se o expoente, a vírgula anda uma casa decimal para a esquerda;

$5*10^{-1}=5*0,1=0,5\\5*10^{-2}=5*0,01=0,05\\5*10^{-3}=5*0,001=0,005\\5*10^{-4}=5*0,0001=0,0005\\5*10^{-5}=5*0,00001=0,00005\\5*10^{-6}=5*0,000001=0,000005\\5*10^{-7}=5*0,0000001=\boxed{0,0000005}$
