Final answer:
The result of the formula =C6+D6*3 is 19, calculated by first multiplying the value of cell D6 (5) by 3, and then adding that result (15) to the value of cell C6 (4).
Step-by-step explanation:
The result of the formula =C6+D6*3, where cell C6 contains the value of 4 and cell D6 contains the value of 5, can be calculated by first performing the multiplication and then the addition, based on the order of operations commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). In this case, you would first multiply the value in D6 by 3, resulting in 5*3, which equals 15. Then, you would add this result to the value in C6, so 4 + 15, which gives a final result of 19.
