Step-by-step explanation:
20 divided by 2
10
---
28 - 10
18
3^2 is 9
so, 9 x 18 = 162.
Let's break it down again, just for extra clarification.
20÷2 = 10
28 - 10 is 18.
3^2 is 9.
9 x 18 = 162
The answer is 162.
Following the order set out in the acronym PEMDAS
[P- parenthesis, E- exponents, M- multiplication, D- division, A- addition, S- subtraction ]
given 3² × (28 - 20 ÷ 2)
= 9 × (28 - 10)
= 9 × 18
= 162
