explain how to solve 8^2 + 9 (12/3x2)-7?
plzzzzzzzzzz help me!!
In computer typing * is used for multiplication and / is used for division, so your question is
8^2 + 9(12/3*2) - 7
= 64 + 9(8) -7
= 64 + 72 - 7
= 129

Welcome
:)
i think it is 12 divided by 3 times 2
how do i simplify this?
Sure! I can help you with that. To solve the expression, we'll use the order of operations, also known as PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break down the expression step by step:
1. First, we'll perform any calculations inside parentheses. However, there are no parentheses in this expression, so we can move to the next step.
2. The next step is to evaluate any exponents. In this case, we have an exponent of 2 on 8. To calculate 8^2, simply multiply 8 by itself: 8^2 = 8 * 8 = 64.
3. Now, we'll handle multiplication and division from left to right. In the expression, we have multiplication and division combined. So, it's important to follow the left-to-right order.
a. Let's begin with 12/3, which equals 4.
b. Next, we multiply this result by 2: 4 * 2 = 8.
c. Now, we multiply 9 by 8: 9 * 8 = 72.
4. Finally, we'll perform addition and subtraction from left to right. In this case, we only have subtraction.
a. Subtract 7 from 72: 72 - 7 = 65.
So, the solution to the expression 8^2 + 9 (12/3x2)-7 is 65.
Oops! I forgot a step.
Thanks, Reiny!
8^2 + 9 (12/3x2)-7
64 + 2 - 7 = 59
Or -- depending upon how (12/3x2) is interpreted -- it could be:
64 + 6 - 7 = 63
