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

Answer:
40
Step-by-step explanation:
divide by 5 if there is a decimal it is wrong
12.5/5=2.5
62.5/5=12.5
40/5=8
112.5/5=22.5
Answer:
the correct answer is 26 hope this help!
A farmer collected 12 dozen eggs from her chickens. She sold 5/6 of the eggs at the farmers' market, and gave the rest to friends and neighbors. Then 2 dozens did the farmer give away
A division is a process of splitting a specific amount into equal parts.
Given that a farmer collected 12 dozen eggs from her chickens
We know that 1 dozen = 12 eggs.
12 dozens = 12×12=144 eggs.
And out of 144 eggs, she sold 5/6 of the eggs at the farmer market, that is
5/6×144
120 eggs.
And she gave away the rest to friends and neighbours .
It means, she gave 144-120=24 eggs.
to friends and neighbours, which is equal to 2 dozens .
Hence, 2 dozens of eggs she gave away.
