A nonzero polynomial with rational coefficients has all of the numbers [1 sqrt{2}, ; 2 sqrt{3}, ;3 sqrt{4},; dots, ;1000 sqrt{10
Colt1911 [192]

Answer:

Its degree can be at least 1970

Step-by-step explanation:

for each root of the form √q, where q is not a square, we have a root -√q. Therefore, we need to find, among the numbers below to 1000, how many sqaures there are.

Since √1000 = 31.6, we have a total of 30 squares:

2², 3², 4², ...., 30², 31²

Each square gives one root and the non squares (there are 1000-30 = 970 of them) gives 2 roots (one for them and one for the opposite). Hence the smallest degree a rational polynomial can have is

970*2 + 30 = 1970

Sandy has 18 roses, 9 daisies, and 45 tulips. She wants to arrange all the followers in bouquets. Each bouquet has the same numb
uranmaximum [27]

Answer:

Greatest number of flowers in a bouquet = 9 flowers

Step-by-step explanation:

Total no. of roses = 18

Total no. of daisies = 9

Total no. of tulips = 45

To find the greatest no. of flowers that can be arranged in the bouquet such that there are same number of flowers and same type of flowers in the bouquet, we will take the H.CF (highest common factor) of 18,9,45

H.C.F of 18,9,45 = 9

Hence, the greatest number no. of flowers that can be arranged in the bouquet = 9 flowers.
