Question

Perform the following operationand express the answer inscientific notation.5.7365x10-5 = 3.4891x10-8[ ? ]x10?)Coefficient (green)Exponent (yellow)Enter

Answer 1

`\begin{gathered} (5.7365\cdot10^(-5))/(3.4891\cdot10^(-8))= \\ =(5.7365)/(3.4891)\cdot(10^(-5))/(10^(-8))=\text{ separating by similar terms} \\ =1.64412026\cdot10^(-5-(-8))=\text{ calculating each division separately} \\ =1.6441\cdot10^3\text{ rounding} \end{gathered}`

Both numerator and denominator have 5 significant figures, then the quotient will have 5 significant figures too.
