Answer is
When it's powered numbers, remember to choose the one with the largest power. For example,
And
Choose 10, same goes to y, where you choose 7 not 4 since 7 is larger.

Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2 Solve : -7n = 0
Multiply both sides of the equation by (-1) : 7n = 0
Divide both sides of the equation by 7:
n = 0
Solving a Single Variable Equation:
3.3 Solve : n-7 = 0
Add 7 to both sides of the equation :
n = 7
This is what i got! if i’m wrong i’m so sorry
but i tried. have a amazing day☺️☺️
Answer:
2
Step-by-step explanation:
30y x 2 = 60y
To subtract fractions, you need to obtain a common denominator. We can achieve this, in this case, by multiplying:
Simplify this:
Now we have common denominators, so we can easily just subtract the numerators, and we have the answer:
Notice that this is divisible by 2:
That's your answer!
