Ex 12.2, 3 Express the number appearing in the following statements in standard form. (ii) Charge of an electron is 0.000,000,000,000,000,000,16 coulomb. 0.000,000,000,000,000,000,16 coulomb = 16/100,000,000,000,000,000,000 = 16/〖10〗^20 = 16×〖10〗^(−20) = (1.6×10) × 〖10〗^(−20) = 1.6 × (10×〖10〗^(−20) ) = 1.6 × 〖10〗^(1 + (−20)) = 𝟏.𝟔 × 〖𝟏𝟎〗^(−𝟏𝟗) coulomb (Using 𝑎^𝑚×𝑎^𝑛=𝑎^(𝑚 + 𝑛))
