To find: whether the expression simplifications

Answer to Problem 59HP
Incorrect
Explanation of Solution
Given:
Concept Used:
BODMAS Rule:
B Bracket − ( ) or [] or {}
O Order or Power -
D Division
M Multiplication
A Addition
S Subtraction
Calculation:
Solving the term having round brackets ( ) within the square brackets [ ] (Q BODMAS Rule)
In simplification 1, the term having power term is solved before than the term having brackets, which is violating the BODMAS Rule.
Further, in simplification 2, the term 10 in brackets with the term 9 are subtracted before multiplying with the term 4, which is violating the BODMAS Rule.
Solving the term having order
Solving the expression within square brackets [ ] (Q BODMAS Rule)
Solving the term having round brackets ( ) (Q BODMAS Rule)
Conclusion:
Therefore, according to BODMAS rule: Both simplifications are incorrect
