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.
Hello!
To solve this , we will use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). We will do so below.
First we solve the parentheses.
7·(8^2)-3^2
7(64)-3^2
Next, we solve the exponent.
7·(64)-9
The next thing we have is multiplication. We multiply the numbers right next to each other, going left to right, as shown below.
448-9
Now, we subtract.
439
Therefore, our answer is 439.
I hope this helps!
