WebAnswer: SOLUTION: Prime numbers less than 20 are 2, 3, 5, 7, 11, 13, 17 and 19. (i) 2+3=5 (divisible by 5) (ii) 2+13= 15 (divisible by 5) (iii) 3+7=10 (divisible by 5) (iv) 3+17= 20 (divisible by 5) (v) 7+13=20 (divisible by 5) Video transcript Hello, strains. Let us go to question number 11. WebApr 7, 2024 · 7 x 13 is about 100 = 10^2. So, we are left with: 2 x 3 x 11 x 17. 2 x 3 x 17 is about 100 = 10^2. Finally, we have 11, which is about 10 = 10^1. Thus, the product of all the prime numbers less than 20 is closest to 10^2 x 10^2 x 10^2 x 10^1 = 10^7. Answer: C. S.
