Question: Working to 4dp, evaluate (a)By evaluating each term and then summing, (b) By nested multiplication Assuming that the number 1.65 is correctly rounded and

Working to 4dp, evaluate

E = 11.65+(1.65)-(1.65)+ (1.65)+

(a) By evaluating each term and then summing,

(b) By ‘nested multiplication’

E = 1 + 1.65(-1 + 1.65(+1.65(-+(1.65))))

Assuming that the number 1.65 is correctly rounded and that all other numbers are exact, obtain error bounds for both answers.

E = 11.65+(1.65)-(1.65)+ (1.65)+
