Question

Miguel’s steps in evaluating an expression are given below. 32/2(2^3-4) Step 1: =32/2(8-4) Step 2: =32/2(4) Step 3: =32/8 Step 4: =4 What, if any, was Miguel’s mistake? Miguel made no mistakes. Miguel incorrectly evaluated 2³ in step 1. Miguel incorrectly multiplied before dividing in step 3. Miguel should have used the distributive property in step 1.

Answer 1

Answer:

C. Miguel incorrectly multiplied before dividing in step 3

Step-by-step explanation:

We are gievn,

The steps of evaluation of the expression $L=\frac{32}{2}(2^3-4)$ are given by,

Step 1: $L=\frac{32}{2}(8-4)$

Step 2: $L=\frac{32}{2}(4)$

Step 3: $L=\frac{32}{8}$

Step 4: L = 4

We see that Miguel evaluated the expression wrong at the step 3, where the correct evaluation is given by,

Step 1: $L=\frac{32}{2}(8-4)$

Step 2: $L=\frac{32}{2}(4)$

Step 3: $L=32\times 2$

Step 4: L = 64

Thus, the mistake made by Miguel is given by,

C. Miguel incorrectly multiplied before dividing in step 3
