The simplified form of the expression 8 + (-7)² - (7 × (-2) + 1 ) is 70.
What is the simplified form of the expression?
Given the expression in the question;
8 + (-7)² - (7 × (-2) + 1 )
Simplify each term, raise -7 to the power 2
8 + (-7)² - (7 × (-2) + 1 )
8 + 49 - (7 × (-2) + 1 )
Multiply 7 by -2
8 + 49 - ( -14 + 1 )
Add -14 and 1
8 + 49 - ( -13)
Remove parenthesis by multiplying -1 by -13
8 + 49 + 13
Now, simplify by adding the number
8 + 49 + 13
57 + 13
70
Therefore, the simplified form of the expression 8 + (-7)² - (7 × (-2) + 1 ) is 70.
