Answer: 564348879
Explanation:
To solve the expression (647+647)756x578-5476-989+45+67, follow the order of operations, which is often remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right):
First, calculate the sum inside the parentheses:
(647+647) = 1294
Next, multiply the result by 756:
1294 x 756 = 977064
Then, multiply the previous result by 578:
977064 x 578 = 564355232
Subtract 5476:
564355232 - 5476 = 564349756
Subtract 989:
564349756 - 989 = 564348767
Add 45:
564348767 + 45 = 564348812
Finally, add 67:
564348812 + 67 = 564348879
Therefore, the result of the expression (647+647)756x578-5476-989+45+67 is 564348879.
