Find the correct result . Remember the maths is exact
1+4=5
2+5=12
3+6=21
5+8=____.
The answer is not 34 and 45 please solve this for me

Method 1.
→ 1 + 4 = 5
= (1×4) + 1 = 5
→ 2 + 5 = 12
= (2×5) + 2 = 10 + 2 = 12
→ 3 + 6 = 21
= (3×6) + 3 = 18 + 3 = 21
If we notice carefully the above formula is like (X × M) + X
What multipled is added again. First one multiplied with four and one is added again. Then, two multiplied with five and two is added again and so on.
Next case will be like:
[ 4 + 7 = 32
(4×7) + 4 = 28 + 4 = 32 ]
→ 5 + 8 = 45
= (5×8) + 5 = 40 + 5 = 45
Therefore,
5 + 8 = 45
Method 2.
First one is simple adition i.e. 1 + 4 = 5. Nothing can be added, subtracted, squared, multiplied, divide etc.
Now, let's come to the second one i.e.
2 + 5 = 12
But 2 + 5 = 7. Now, subtract 7 from 12 (12 - 7 = 5). On subtracting we get 5.
So, 2 + 5 + (5) = 12
Similarly,
3 + 6 = 21
But 3 + 6 = 9. Again, subtract 9 from 21, we get 12.
So, 3 + 6 + (12) = 21
What we get after addition, we are adding the same number in the second one and getting the result.
Therefore,
→ 1 + 4 = 5
→ 2 + 5 + (5) = 12
→ 3 + 6 + (12) = 21
[ 4 + 7 + 21 = 32 ]
→ 5 + 8 + (32) = 45
Answer:
45
Step-by-step explanation:
1 + 4 = 5
We may write it as: (1×4) + 1 = 5
2 + 5 = 12
We may write it as: (2×5) + 2 = 12
Similarly, 3 + 6 = 21 can be written as: (3×6) + 3 = 21
So, we conclude that, each equation can be represented in the form of
(x × y) + x.
(This means, the number that is multiplied with another number is added again with the product)
So, the next equation will become like this:-
4 + 7 = (4×7)+4 = 28 + 4 = 32
Now, 5 + 8 = (5×8) + 5
= 40 + 5
= 45
∴Thus, 5 + 8 is equal to 45.
