Hey! :)
Some things to note: When you bring a exponent to the numerator, you make it negative.
When you put an exponent to another exponent, you multiply the exponents together.
so that is your answer, please let me know if you need more of an explanation. :)
15x over 2 dont know how to do it on computer
0.250*140,000,000=35,000,000
40,000,000/35,000,000= 1.14
So about 1 time
Answer:
The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.
Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.
In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.
