Final answer:
To simplify the denominator on the right side of the equation, we can replace the square root of 4a² with 2a.
Step-by-step explanation:
To simplify the denominator on the right side of the equation, we can use the fact that the square root of 4a² is 2a.
This means that whenever we see the expression √(4a²), we can replace it with 2a in our calculations.
For example, if we have an expression like √(4a² + 5), we can simplify it by replacing √(4a²) with 2a, giving us 2a + √5.
This makes the calculation easier and allows us to work with simpler expressions.
