Answer:
only (2) and (4) are polynomial out of given options.
Step-by-step explanation:
Polynomial is an expression having variables having positive integer exponents with real constant coefficients. example
We are given some polynomials and we have to choose whether are polynomial or not.
Consider ,
1)
Since, Polynomial does not have a fractional exponent.
So, 1) Not a polynomial.
2)
Since all of the variables have integer exponents that are positive this is a polynomial.
3)
Not a polynomial because a term has a negative exponent .
4)
Since all of the variables have integer exponents that are positive this is a polynomial.
Thus, only (2) and (4) are polynomial out of given options.
Answer:
(repeating, which is usually signified by a line over the 6, but I couldn't type that)
Step-by-step explanation:
________
15 | 4
__._____
15 | 4 0 since 15 is bigger than 4, add a 0 here.
make sure you also place a decimal point
above (above the place directly after 4) so your
answer isn't larger than it should be.
__.2____
15 | 4 0
3 0 15*2 = 30. that's as close to 40 as we're going to get.
__.2____
15 | 4 0
<u>-30 </u>
10 40 - 30 = 10.
__.2____
15 | 4 0
<u>-30 </u>
1 0 0 bring down an imaginary 0.
__.26___
15 | 4 0
<u>-30 </u>
1 0 0
<u> - 90 </u> 15*6 = 90. that's as close to 100 as we're going to get.
1 0
Notice that we keep getting 10 as a remainder again if we keep going. So 6 keeps repeating on top, which is why it's a repeating decimal. Once you realize it's the same number again and again the further you divide it, you can stop and write the line over the 6.
