How many time is 3.4x10 to the 10 power than 1.7x 10 to the 8 power

3.4*10=34. 34^10

1.7*10=17. 17^8

To begin, I'm not sure what you're asking, but I'll tel, you that 17 is half of 34. So, 17^8 is going to be less than 34^10.

Specifically, 34^10 is going to be 2*17*17*17*17 times more than 17^8
