Question

how many times greater 3x10^4 than 4x10^2

Answer 1

if 10 to the 4th power is 10,000, and 10 to the second power is 100, and multiply 3 by 10,000 which would be 30,000, and 4 by 100, it would be 400, so your answer is 29600. I hope this helps! Also if I am wrong, please tell me, I did the best I could with the information I had. 

Answer 2

$\dfrac{3\cdot10^4}{4\cdot10^2}=\dfrac{3}{4}\cdot10^{4-2}=\dfrac{3}{4}\cdot10^2=\dfrac{3}{4}\cdot100=3\cdot25=\boxed{75}$

So 3*10⁴ is 75 times greater than 4*10²
