Noah reads the problem, "Evaluate each expression, giving the answer in scientific notation." The first problem part is: 5.4 x 10⁵ +2.3 x 10⁴. Noah says, "I can rewrite 5.4 x 10⁵ as 54 x 10⁴. Now I can add the numbers: 54 x 10⁴ +2.3 x 10⁴ = 57.3 x 10⁴
Do you agree with Noah's solution to the problem?
