Question

9 times 10 to second power is ___ times grater than 3 times 10 to the -2

Answer 1

(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
