Answer:
14
Step-by-step explanation:
10 questions = 4 correct + 6 incorrect
4 correct = 4* 5 = 20
6 incorrect = 6* (-1) = -6
His score is 20 -6 = 14 points
The answer to this exponential expression is 439.
To solve this expression, we need to use pemdas (parenthesis, exponents, multiplication, division, addition, subtraction). That measn that we first have to do the parenthesis.
7 * (8)² - 3²
Now we have to do exponents.
7 * 64 - 9
Now we have to do the multiplication (because of the order of pemdas)
448 - 9
Finally, we do the subtraction
439. That means that the answer to this exponential expression is 439.
