Find Significant Difference of 1.7x10^5 & 1.49x10^6

[marquitos]

can someone give me a fomula to determine the significant difference of the difference in cells/mL in the sample our graph shows 1.7×〖10〗^5 and 1.49×〖10〗^6 how do i find if these numbers are significantly different?
I know this is very broad and really doesn't give you much to work with but all i can give you is also the range of our answers and that is 1.7×〖10〗^5 is the lowest and 1.7×〖10〗^6 is the highest data point

thank you so much again

To determine significance you need to have at least 3 measurements at each datapoint. The range you give is for different datapoints (different concentrations), isn't it?
