Answer:

a=2, b=5

Step-by-step explanation:

Let

n -----> the denominator

we have

$3.5*10^4=\frac{7*10^9}{n}$

Solve for n

That means -----> isolate the variable n

Multiply by n both sides

$3.5*10^4(n)=7*10^9$

Divide by 3.5*10^4 both sides

$n=\frac{7*10^9}{3.5*10^4}=(\frac{7}{3.5})(\frac{10^9}{10^4})=2*10^5$

therefore

a=2, b=5
