Thanks for showing your work. It helps us to know where you are having trouble.
#4. [25/ (2^3-3)]*2 the star two represents multiplied by 2
My way of solving:
[25/(8-3)]*2 (this was suppost to be-
[25/5]*2 multiplied by 2)
[5]*2 You are ok to here. 5^2 = 25 and not 10.
My answer:10 ( then my answer is 10) is this correct

Yes, 10 is correct.
thank you

I went back and looked at the original problem and it is posted the same way here as it was originally; therefore, I am the one that made the mistake. I misread the * (meaning multiplied by) for a caret (^--meaning raised to the power). So your original answer of 10 was correct then as it is correct now.
In this scenario, the question involves simplifying an expression. Let's break it down step by step to understand how to arrive at the answer.
The original expression is: [25/ (2^3-3)]*2
1. First, we need to evaluate the exponent in the parentheses: 2^3. This means raising 2 to the power of 3, which is 8.
So, the expression becomes: [25/ (8-3)]*2
2. Next, we simplify the subtraction in the parentheses: 8-3, which equals 5.
The expression now becomes: [25/5]*2
3. Now, we divide 25 by 5: 25/5 = 5.
The expression becomes: 5*2
4. Finally, we multiply 5 by 2: 5*2 = 10.
Therefore, the final answer is 10.
