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
