Question

(-2^5(3^5)^2) ÷(12×3^7)​

Answer 1

Step-by-step explanation:

Thus in the first equality 1+4 = 5, the first two digits are 1 and 4. Multiply them to get the result 4. Then add the first digit 1 to this 4. The result is 5, the RHS. In the same manner, for the second equality, we write, 2x5=10 and 10+2=12, the RHS. For the third equality, it is (3x6) + 3 = 18 + 3 = 21.

Applying the above rule to evaluate 5+8, we write 5x8=40 and then add 5 to it to arrive at the answer 45.

PS: Having answered the question in the expected way, I want to point out a flaw in the framing of or writing the question. ‘+’ is the universal symbol for addition of numbers or union of sets. Instead of + sign, we should have OP sign meaning ‘operating on’. Thus the question should have been written, 1 OP 4 instead of 1+4, 2 OP 5, 3 OP 6 and 5 OP 8. Then the readers have to discover the rule associated with the OP sign.
