Option A

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

<em><u>Product of powers property:</u></em>
The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents
Which is represented as,

<em><u>Therefore, the given expression becomes,</u></em>

Now add the exponents, we get

Simplify the above expression

Simplify the exponent of y, we get

Thus Option A is correct
Factorial is the correct answer because in combinations the order does not matter
The reciprocal of a number is the number that the first number will multiply with that equals one.
So, for instance, the reciprocal of 3 is 1/3.
Since we can write 3 as 3/1, we can see it's simply flipping the numerator and denominator to find the reciprocal.
So, flipping numerator and denominator, the reciprocal of 31/2 is 2/31.
Answer:
Step-by-step explanation:
Let the numbers be y, y+2, y+4
3(y+2)=153
3y+6=153
3y=153-6
3y=147
y=49
y+2=51
y+4=53
