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:
2/3
Step-by-step explanation:
Numerator is 12-2-8
Denominator is 1*3
2/3
3(x - 2) - 5x = 18
The required simplifiedvalue of the x for the given expression is -2.
Given that,
To determine the value of the x for the expression 3(x - 2) - 5x = 18.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
3(x - 2) - 5x = 18
Simplifying the above equation,
3x - 6 - 5x = 18
3x - 5x = 18 + 6
-2x = 24
x = 24 / -2
x = -12
Thus, the required simplifiedvalue of the x for the given expression is -2.

Hi there!
To solve your answer, since we know a = 7, we can easily solve your equation.
But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.
When you have a number, and a variable attached to it, it means to multiply.
Now, to make this equation look a little easier, lets rewrite it.
9 × 7 - 5 × 7 = ___
According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.
9 × 7 = 63.
5 × 7 = 35.
Now, since we've multiplied the two numbers, its time to subtract them.
63 - 35 = 28. Sooooo........
9 × 7 - 5 × 7 = 28
Hope this helps!
