Calculate the answer to the correct significant figures and

Calculate the answer to the correct significant figures and propagate the error of the respective tolerances for the expression: (289.24(

Solution

Correct significant figures : 74 + 655.87 * 0.1548 = 175.52

Propogation of error:

(74-16) + (655.87-16.28) * (0.1548-0.0286) = 138.71

to

(74+16) + (655.87+16.28) * (0.1548+0.0286) = 213.27
