Insert parentheses to make the statement true;
6 x 5 - 2^2 = 45
6 x (5 - 2)^2 = 45
To insert parentheses to make the statement true, we need to follow the order of operations (PEMDAS/BODMAS). This means that we need to calculate the exponentiation (2^2) first, then perform the multiplication (6 x 5), and finally perform the subtraction.
Let's go step by step:
1. Start with the original equation: 6 x 5 - 2^2 = 45
2. Calculate the exponentiation: 2^2 = 4
The equation becomes: 6 x 5 - 4 = 45
3. Perform the multiplication: 6 x 5 = 30
The equation becomes: 30 - 4 = 45
4. Finally, subtract: 30 - 4 = 26
Therefore, the statement 6 x 5 - 2^2 = 45 is not true.
