2^3+6-5X4=12
show how to solve and show operation
To solve the equation 2^3 + 6 - 5 * 4 = 12 and show the operations, we follow the order of operations (also known as PEMDAS or BIDMAS):
Step 1: Start by calculating the exponent. In this case, 2 raised to the power of 3:
2^3 = 2 * 2 * 2 = 8
The equation becomes: 8 + 6 - 5 * 4 = 12.
Step 2: Next, perform the multiplication:
5 * 4 = 20
After substitution, the equation becomes: 8 + 6 - 20 = 12.
Step 3: Now, perform the addition:
8 + 6 = 14
After substitution, the equation becomes: 14 - 20 = 12.
Step 4: Finally, solve the subtraction:
14 - 20 = -6
The final equation becomes: -6 = 12, which is false.
Therefore, the original equation 2^3 + 6 - 5 * 4 = 12 has no solution.
