526 x 637 + 448 / 637 x 527 - 189
= 526 x 637 + 448 / 637 x ( 526 + 1 ) - 189
= 526 x 637 + 448 / 637 x 526 + 637 - 189
= 526 x 637 + 448 / 637 + 526 + 448
= 1
k mik nhé
526 x 637 + \(\frac{448}{637}\)x 527 - 189
= 526 x 637 + \(\frac{448}{637}\)x ( 526 + 1 ) - 189
= 526 x 637 + \(\frac{448}{637}\)x 526 + 637 - 189
= 526 x 637 + \(\frac{448}{637}\)x 526 + 448
= 1
