(9• 10^2) •? > 3•10^-2

We can rewrite the the firsts part to something equivalent to make it look like the second part of inequality.

3•3•10^2. • 10^-2. •10^2 > 3•10^-2

Use commutative property of multiplication

(3•10^-2) (3• 10^2. •10^2) > 3•10^ - 2

(3• 10^-2) • (3• 10^4) > 3•10^ - 2

So the answer is 3•10^4 greater
