Let `a=111 1(55d igi t s),b=1+10+1=^2++10^4,c=1+10^5+10^(10)+10^(15)++10^(50),` then `a=b+c` b. `a=b c` c. `b=a c` d. `c=a b`

A

a+b+c

B

a=bc

C

b=ac

D

c=ab

Text Solution

Verified by Experts

The correct Answer is:
B
`a=1+10+10^(2)+….+10^(54)`
`=(10^(55)-1)/(10-1)=(10^(55)-1)/(10^(5)-1)xx(10^(5)-1)/(10-1)=bc`
