Find the HCF of 315 and 600 by using Euclid's division algorithm
2. If A = {3,9,27,81), then write A in the set builder form.
3. If A = (x:x e N and x < 15) and B= (x:x
B= (x:x e N and x <3).
then find A-B and write it in the set builder form.
4. Sum of the zeroes of the polynomial p(x)=x? - kx + 9 is 7. Find th
value of K.​

Answer 1

Step-by-step explanation:

1•HCF of 315 and 600

HCF = 1

2• A={x:x is 3 to the power of a , a e N, a< 3}

3•A={1,2,3,4,5,6,7,8,9,10,11,12,13,14}

B={1,2}

4• (-2)x+9

k=7x
