Marcus and Jeremy both evaluated the expression - 5 ^ 2 + 3. Marcus said the answer was -22. Jeremy said the answer was 28. Who is correct? Explain the error in the other student's work. 1-2 sentences
Jeremy is correct. Marcus made an error by not following the order of operations and incorrectly calculated the exponent first, resulting in the incorrect answer of -22.
Jeremy is correct. Marcus made an error in the order of operations. The exponentiation should be done first, so the correct calculation is -5^2 + 3 = -25 + 3 = -22.
Jeremy is correct. The error in Marcus' work is that he incorrectly evaluated the exponent before the negation: (-5)^2 = 25, so the correct expression is -5^2 + 3 = -22+3 = -19, not -22.
