Answer:
Step-by-step explanation:
Given, 4- 3 -7 =42
= 7² - ( 4² + 3²)
= 49 - ( 16 + 9)
= 49- 25
= 24
Reverse of 24 is 42
(2) 8 - 6 - 3 = 91
= 8² - ( 6² + 3²)
= 64 - ( 36-+9)
= 64 - 45
= 19
reverse of 19 is 91
So , 9 -5 -3
9² - ( 5² + 3²)
81 - (25 + 9)
81 - 34
= 47
Reverse of 47 is 74
So the answer is 74
