Question 1 & 2
Question 1: Evaluate
FPSC AD IB 2017
Solution:
How any thing having power zero becomes 1 ?
we generally know;
Why? It is because each ‘x’ has power 1 in above fraction i-e
Comparing both expressions for same ration we get;
____________________________________________
If any figure or amount has exponent or power of zero ‘0’ then its value is equal to 1
I- e
if zero has power zero, then result is undefined i-e
Because division by zero is not allowed in maths, so,
So, in the asked question 10 has power 0, so its value is equal to 1, so we solve it;
Question 2: What is missing term in the sequence 2,6,18,_,162 ?
FPSC AD IB 2017
Solution:
If we multiply 2 with 3 it gives 6
if we multiply 6 with 3 it gives 18
and so on ……………………..
I f we divide 18 by 3 , we get 6
If we divide 6 by 3 , we get 2
i-e previous term of sequence is achieved by dividing a term ahead
so, if divide 162 by three, we get 54
so the missing term is 54
