Final answer:
x = 3949
To find the value of x, which equals 8+7*563, you must multiply 7 by 563 first and then add 8 to the result, following the order of operations. This gives us x = 3949.
Step-by-step explanation:
If x equals 8+7*563, then to solve for x, we should follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). Here, we only have multiplication and addition to deal with. So, we need to carry out the multiplication before we do the addition.
The equation x = 8 + 7*563 can be solved as follows:
- Multiplication: 7 * 563 = 3941
- Addition: 8 + 3941 = 3949
Therefore, x equals 3949.
The provided information (xa)b = xa.b is an exponent rule that tells us when we have a power raised to another power, we multiply the exponents. However, this does not directly apply to the original problem, which only involves basic arithmetic operations.
