Oh ok 😊
Thnx
To solve the expression 7^3 - 4 x 3 + 8, we need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
First, we need to solve any exponents. In this case, 7^3 means we need to multiply 7 by itself three times. So, 7^3 is equal to 7 x 7 x 7, which is equal to 343.
Now, let's substitute the value of the exponent into the original expression:
343 - 4 x 3 + 8
Next, we move on to the multiplication and division. Looking at the expression, we see that 4 x 3 needs to be calculated. 4 multiplied by 3 equals 12.
Now, let's substitute the value of the multiplication into the expression:
343 - 12 + 8
Next, we move on to the addition and subtraction. We start from left to right. In this expression, we subtract 12 from 343 first, then add 8 to the result.
343 - 12 + 8 equals 339.
So, the final answer to the expression 7^3 - 4 x 3 + 8 is 339.
Therefore, the first operation in the expression was an exponent. (A) An exponent.
