18(x + y)3, 24(x + y)2 এবং 32(x2 - y2) এর গ.সা.গু কোনটি?
Solution
Correct Answer: Option A
১ম রাশি= 18(x + y)3
= 2 . 3 . 3 (x + y)(x + y)(x + y)
২য় রাশি= 24(x + y)2
= 2 . 2 . 2 . 3 (x + y)(x + y)
৩য় রাশি = 32 (x2 - y2)
= 2 . 2 . 2 . 2 . 2 (x + y)(x - y)
∴ রাশিগুলোর গ.সা.গু = 2(x + y)
= 2 . 3 . 3 (x + y)(x + y)(x + y)
২য় রাশি= 24(x + y)2
= 2 . 2 . 2 . 3 (x + y)(x + y)
৩য় রাশি = 32 (x2 - y2)
= 2 . 2 . 2 . 2 . 2 (x + y)(x - y)
∴ রাশিগুলোর গ.সা.গু = 2(x + y)
