Question

Arrange the following in descending order. 2by9,2by3,8by21

Answer 1

Answer:

8by21 > 2by9 >2by3

Step-by-step explanation:

Since all the numbers have by, let's just assume their values since it won't make any difference.(You can also just ignore them and write 2by9 just as 2*9)

I'm taking :-

b = 1

y = 2

Therefore

i) 2by9 = 2 * 1 * 2 * 9

= 36

ii) 2by3 = 2 * 1 * 2 * 3

= 12

iii) 8by21 = 8 * 1 * 2 * 21

= 273

Therefore

273 > 36 > 12

8by21 > 2by9 >2by3
