Answer:
77
Step-by-step explanation:
to start off the "difference" is the way to say total in subtraction
you would have to subtract 87 and 10 to find the difference
87 - 10 = 77
77 is the difference between their times
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.
