Question

Suppose we have 0.2360, here we have 4 significant figures but if we change the unit so that it is written as 236 × 10^-3 then the significant figures are only 3, but as we all know, s.f don't change on changing the units. Plz help

Answer 1

Answer:

significant figures can change when the numbers are represented in different forms,in different units

this is the reason why we use the decimal notation like u have done in the second example 236 × 10⁻³

because 0s after decimals do not cause trouble in this form

but the correct representation would be

2.36*10⁻²

I hope this helps you friend!
