Answer:So, the maximum value of the relative error is 0%.
Step-by-step explanation:Relative error = (absolute error / actual value) * 100% In this case, we need to find the maximum value of the relative error for the given expression: u = 5xy^2/z^3 Given that x = y = z = 1, we can substitute these values into the expression: u = 5(1)(1^2)/(1^3) = 5(1)/1 = 5 Since there are no uncertainties or errors in the values of x, y, and z, the absolute error is zero. Therefore, the relative error is also zero: Relative error = (0 / 5) * 100% = 0% So, the maximum value of the relative error is 0%.
