Jamie says the value of 1.43 Γ (β 18/35) is close to β0.75. student a says this estimate is reasonable because the product is negative and about half of 1.5. student b says you could find the product using a calculator as follows: "divide β18 by 35, multiply the quotient by 1.43, then round the product to the nearest hundredth." does student b's approach to find the product justify the claim that jamie's estimate is reasonable?
