Nciado: frequentemente, em ciências exatas, utilizamos potências de base 10 para expressar números muito grandes ou muito pequenos. para as potências de base 10 mais utilizadas foram desenvolvidos os prefixos e símbolos. por exemplo, o prefixo centi (simbolizado pela letra minúscula c) se refere à potência 10-2. então, se fizermos uma medida de 0,01 metro, ela poderá ser escrita como 1.10-2m ou, então, como 1 cm (um centímetro). existem vários outros prefixos, é importante saber usá-los corretamente e adotar a simbologia adequada. dentre as opções abaixo, qual seria a opção correta para escrevermos a medida de 30 000 gramas (g) em potência de base 10? escolha uma:
