Answer 2

Answer:

C. 3(-4) - 2 × 36

Step-by-step explanation:

The question 3(4-8) - 2 × 6^2 requires the use of BIDMAS

Rule.

First, solve the problem in the brackets thus:

3(-4) - 2 × 6^2

Then solve the problem in index form which is 6^2. Note that 6^2 implies 6 × 6 = 36. Thus:

3(-4) - 2 × 36

Therefore, the equivalent expression of 3(4-8) - 2 × 6^2 is

3(-4) - 2 × 36
