Will someone please help me

Answer 1

`4.53 * 10^(- 1)`

Explanation:

We have to divide
`1.6 * 10^(- 10)` by
`3.53 * 10^(- 10)` and we have to write the answer in scientific notation.

Now,
`(1.6 * 10^(- 10)) / (3.53 * 10^(- 10))`

=
`((1.6)/(10^(- 10)))/ ((3.53)/(10^(- 10)))` {Since using the property of exponent
`x^(- a) = (1)/(x^(a) )` }

=
`((1.6)/(10^(- 10))) * ((10^(- 10))/(3.53) )`

{Since we know the mathematical operation
`(a)/(b) / (c)/(d) = (a)/(b) * (d)/(c)` }

=
`(1.6)/(3.53)`

= 0.45325

=
`4.53 * 10^(- 1)` (Answer) {Rounded the coefficient to two decimal places}
