Answer:
a=2, b=5
Step-by-step explanation:
Let
n -----> the denominator
we have
[tex]3.5*10^4=\frac{7*10^9}{n}[/tex]
Solve for n
That means -----> isolate the variable n
Multiply by n both sides
[tex]3.5*10^4(n)=7*10^9[/tex]
Divide by 3.5*10^4 both sides
[tex]n=\frac{7*10^9}{3.5*10^4}=(\frac{7}{3.5})(\frac{10^9}{10^4})=2*10^5[/tex]
therefore
a=2, b=5
