Answer:
Step-by-step explanation:
To solve this expression, we need to follow the order of operations or the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction) and work from left to right.
72 ÷ 12 [180 ÷ 4 {10 + (15 - 45 ÷ 9 × 2)}]
= 72 ÷ 12 [180 ÷ 4 {10 + (15 - 10)}] // 45 ÷ 9 × 2 = 10
= 72 ÷ 12 [180 ÷ 4 {10 + 5}]
= 72 ÷ 12 [180 ÷ 4 × 15]
= 72 ÷ 12 [45 × 15]
= 72 ÷ 12 [675]
Next, we need to evaluate the expression inside the innermost braces:
10 + (15 - 45 ÷ 9 × 2) = 10 + (15 - 10) // 45 ÷ 9 × 2 = 10
= 10 + 5
= 15
Substituting this value in the original expression, we get:
72 ÷ 12 [180 ÷ 4 {15}]
= 72 ÷ 12 [180 ÷ 60]
= 72 ÷ 12 [3]
= 6 [3] // Division first, then multiplication
= 18
Therefore, the final answer is 18.
