Uncertainty problem

I wanted to know if my working is correct here (the uncertainty looks unclear at the right end of the answer dash line, it is 1.57x10^13)

Please tell me how it should be then if I am not correct. I did (deltaGradient)/(Gradient)=(deltaN)/N, is it supposed to be like that given Gradient=(NkT/A)? Gradient have an uncertainty I got the value in the previous question

I am asking because uncertainties to a large power seems vague like 1.57x10^13. So please reply back as soon as possible, I have planning and analysis paper for physics tomorrow.

Here is my working

Did you calculate uncertainty too in gradient in the last part/s? if yes, then use uncertainty(in gradient) + gradient to calculate value of N again. Subtract the new N value from that N value in which you used gradient only to find the uncertainty. I'll explain if you still dont understand..
