Answer:
A is the answer.
Step-by-step explanation:
2 is the index for this expression.
The index used to simplify the radical expression 25x^4y^6 to 5x^2y^3 is 2 (option A), because each part of the expression was divided by 2 or rather, the square root was taken.
The question is asking about simplifying radicals, specifically what index was used. A key point is to remember that a radical is the inverse operation of applying an exponent, so the unknown index signifies how many times the base (25x^4y^6) in the radical would be multiplied by itself to reach the simplified form (5x^2y^3).
In this case, the index that we used to simplify the radical is 2. This is because the square root was taken of all parts of the under the radical sign and as a result, each part of the expression under the radical was divided by 2. So 25 became 5, x^4 became x^2, and y^6 became y^3. That indicates that the index is 2. Therefore, the answer is A. 2
