Answer:

Step-by-step explanation:
To begin simplifying this, we can first divide the coefficients, giving us:

We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:

Now, simplifying this gets:

Answer:
Addition is...
1+1 = 2
But addition irrational numbers is...
π + 5 normally when using pi (π) the numbers are 3.14 but the number is infinite, all irrational numbers are infinite
then the sum will be 3.14 + 5 = 8.14
Answer:
