SOLUTION
Step 1 :
In this question, we were given that:
[tex]a=3.47X10^{-6}^{}[/tex][tex]b=4.61X10^7^{}[/tex][tex]c=5.52X10^7[/tex]Step 2 :
For the first question, we have to do the following calculations:
[tex]\begin{gathered} a.b=(3.47X10^{-6\text{ }})X(4.61X10^7\text{ ) } \\ =15.9967X10^1 \\ =1.59967X10^{1\text{ +1}} \\ =1.60X10^2 \end{gathered}[/tex][tex]\begin{gathered} \frac{a}{b}\text{ = }\frac{3.47X10^{-6}}{4.61X10^7} \\ =0.7527X10^{-6-7} \\ =\text{ }7.53X10^{-1-13} \\ =7.53X10^{-14} \end{gathered}[/tex][tex]\begin{gathered} \frac{c}{a}\text{ = }\frac{5.52X10^7^{}}{3.47X10^{-6}} \\ =1.5907X10^{7--6} \\ =1.59X10^{7+\text{ 6}} \\ =1.59X10^{13} \end{gathered}[/tex]CONCLUSION:
[tex]\begin{gathered} a.b=1.60X10^2^{} \\ \frac{a}{b}=7.53X10^{-14}^{} \\ \frac{c}{a}=1.59X10^{13} \\ \end{gathered}[/tex]
