Final answer:
The expression '146 x 30 + 30 x 54' should be solved by first performing the multiplication operations, resulting in 4380 and 1620. These results are then added together to obtain the final answer of 6000.
Step-by-step explanation:
This mathematical expression involves the operations of multiplication and addition. The expression is: 146 x 30 + 30 x 54.
Firstly, according to the order of operations, or BIDMAS/BODMAS principle, you should perform multiplication operations before addition.
Thus, you multiply 146 by 30, and then 30 by 54.
After doing these, you would get 4380 and 1620 respectively.
Afterwards, proceed to add these two results together.
The calculation is: 4380 + 1620.
The final result would be: 6000.
