Sagot :

Explanation:

The expression given in the question is

[tex](\sqrt[3]{64}-16\div2)(2-4)^2[/tex]

Part C:

Step 1:

Solve the cube root

[tex]\begin{gathered} (\sqrt[3]{64}-16\div2)(2-4)^2 \\ (4-16\div2)(2-4)^2 \end{gathered}[/tex]

Step 2:

Divide within first parenthesis

[tex]\begin{gathered} (4-16\div2)(2-4)^2 \\ (4-8)(2-4)^2 \end{gathered}[/tex]

Step 3:

substract within first parenthesis

[tex]\begin{gathered} (4-8)(2-4)^{2} \\ (-4)(-2)^2 \end{gathered}[/tex]

Step 4:

Substract within the parenthesis

[tex]\begin{gathered} (-4)(2-4)^2 \\ -4_(2-4)^2 \\ -4(-2)^2 \end{gathered}[/tex]

Step 5:

Simplify the exponent

[tex]\begin{gathered} -4(-2)^2 \\ =-4(4) \end{gathered}[/tex]

Step 6:

Multiply

[tex]\begin{gathered} -4(4) \\ =-16 \end{gathered}[/tex]

Part A:

The mistake made in step 2 was that the student substracted first instead of dividing with the first parenthesis first

[tex]\begin{gathered} (4-16\div2)(2-4)^2 \\ (-12\div2)(2-4)^2(WRONG) \\ \\ (4-8)(2-4)^2(CORRECT) \end{gathered}[/tex]

Part B:

The mistake made in step 4 was that the student simplified the exponent first instead of substracting with the second parenthesis and then simplifying the exponent

[tex]\begin{gathered} (-4)(2-4)^{2} \\ -6(2-16)(WRONG) \\ \\ -4(-2)^2 \\ -4(4)(CORRECT) \end{gathered}[/tex]
