Question

Solve (2.58) (1.2×10^-5)/1.9×10^-5​

Answer 1

Explanation:

(2.58) (1.2×10^-5)/1.9×10^-5​;

=(2.58) (1.2×
`(1)/(10^(5) )`)/1.9×
`(1)/(10^(5) )`;

=(2.58)(
`(1.2)/(100000)`)/1.9×
`(1)/(100000)`;

=0.000031/1.9×
`(1)/(100000)`;

=0.0000163×
`(1)/(100000)`;

=0.000000000163;

=1.63×10^-10

Answer 2

`1(299)/(475)`

Explanation:

`\frac{2.58 * 1.2 * {10}^( - 5) }{1.9 * {10}^( - 5) } = (2.58 * 1.2)/(1.9) = (3.096)/(1.9) = (774)/(475) = 1(299)/(475)`
