Question

notação científica 0,000000371?​

Answer 1

Resposta: 0,000000371 = $3,71x10^{-7}$

Answer 2

$\text{OBS.: m\cdot10^n\leftarrow m : mantissa, n : n ^\circ de casas.}$

=====================================

$0,\!000000371$

$00,\!00000371\leftarrow\text{1 casa,}$

$000,\!0000371\leftarrow\text{2 casas,}$

$0000.000371\leftarrow\text{3 casas,}$

$\vdots$

$0000000\underbrace{3,\!71}_m\,\leftarrow\text{ \underbrace{7}_n casas.}$

$\therefore$

$\underline{\boxed{3,\!71\cdot10^{-\,7}}}\,.$

$*\text{ n \rm\acute{e} negativo devido ao fato de 0,000000371 ser decimal.}$
