Question

give me answer question number 9 and 11​

Answer 1

Answer:

Q9 d) b=0, Q11 b) 101

Step-by-step explanation:

In Q9 when b=0 then on lhs (a/b) is not valid as a/b is infinity or not defined.

Q11

(10^22+ 10^20 )/10^20 => (100(10^20)+ 10^20 )/10^20

=> (101* 10^20)/ 10^20 => 101

Answer 2

answers:-

9).Correct option is(D)b=0

11). correct option is (b) 101

explanation:

9).( a/b) ^n= a^n/b^n

b=0, as (a/0)^n = a^n/0^n

division by 0 is not admissible

11).10^22+10^20/10^20

= 10^22-20+10^20-20

= 10^2+10^0

=10^2+1

=100+1

= 101
