Answer 1

Answer:

1. Yes. 2. No 3. No. 4. No

Step-by-step explanation:

co prime means no number coming in the table.

1. 15 = 3 × 5; 22 = 2 × 11.

No numbers are simmilar. Thus it is co prime.

2. 32 = 2 × 2 × 2 × 2 × 2; 24 = 2 × 2 × 2× 3

2 is simmilar in both of them. Thus it is not co prime.

3. 22 = 11 × 2; 11 = 11

11 is simmilar in both the cases. Thus it is not co prime.

4. 25 = 5 × 5; 15 = 5 × 3.

5 is simmilar in both the cases. Thus it is not co prime.
