4x4+3^19

_________ + 50

450

To solve this math problem, we need to follow the order of operations (also known as PEMDAS) which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

1. Start with the exponentiation: 3^19 means multiplying 3 by itself 19 times.

3^19 = 1162261467

2. Next, perform the multiplication: Multiply 4 by 4.

4 * 4 = 16

3. Now, put these results into the equation:

16 + 1162261467 = 1162261483

4. Finally, divide the result by 450 and add 50:

(1162261483 / 450) + 50

At this point, we can switch to a calculator to obtain the exact answer.
