Equação \/

(7,3 . $10^{-23}$ ) × Y = 3.650.000

Dados : (7,3 . $10^{-23}$ ) = 0,0000000000000000000073 gramas

Answer 1

$(7,3\cdot10^{-23})\cdot Y =3.650.000\\ 73\cdot10^{-1}\cdot10^{-23}\cdot Y=5\cdot73\cdot10^4\\ 73\cdot10^{-1-23}\cdot Y=5\cdot73\cdot10^4\\ 73\cdot10^{-24}\cdot Y=5\cdot73\cdot10^4\\ Y= \frac{5\cdot73\cdot10^4}{73\cdot10^{-24}}\\ Y= \frac{5\cdot10^4}{10^{-24}}\\ Y= 5\cdot10^{4-(-24)}\\ Y= 5\cdot10^{4+24}\\ Y= 5\cdot10^{28}$
