b) (3^-5 × 10^-5 × 5^3) ÷ (5^-7 × 6^-5 × 5^5).
Answers
The answer is 34.
As we can see that in the first sum we have given the sum 1+4 and it's genuine answer is 5 according to the defined addition rule but if we will add 0 to 5 , then also the answer will be the same.Hence the sequence goes as such
1+4= 5+0=5
Now we will keep adding ‘the result which we have got in the preceding sum’ to the genuine answer which we are getting on adding the two given numbers.
So , 2+5 gives it's genuine answer as 7 but on adding 5 to it which we have got as result in the preceding sum(1st sum) ,we will get :
2+5=7+5=12
Hence ,we can generalise the formula as:
Let the given numbers whose sum is to be found are ‘a’ and ‘b’ where a is the 1st number and b is the second number, then
a+b = genuine answer according to normal addition rule+ result of the preceding sum
For 1st sum we have taken ‘0’ as the result of the preceding sum. Therefore in 3rd sum:
3+6=9 (genuine answer )+12 (result of the 2nd sum)=21
Hence , 5+8= 13 (genuine answer )+ 21 (result of 3rd sum)=34.
Hope. .it will help....stay tuned
