The level of service exports worldwide increased more than between 1980 and 2010

The increase in level of service exports all over the world between 1980 and 2010 is extremely high which is about 10 folds. The phenomenon of economic globalization which means trading of goods, information and infrastructure between various countries is a major thing that occurred during this time.

B I personally think..

Step-by-step explanation:

Hi,

Use Differential Formula :

d(u(x) • v(x))/dx = u'(x) • v(x) + u(x) • v'(x)

at x = 1 :

d(u(1) • v(1))/dx = u'(1) • v(1) + u(1) • v'(1)

d(u(1) • v(1))/dx = -5 • 6 + 4  • -2

d(u(1) • v(1))/dx = -30 - 8

d(u(1) • v(1))/dx = -38

Hope this helped :)
