Instructions: What will come in place of question mark (?) in the following questions?
3463 × 295 - 18611 = ? + 5883
(23.1)2 + (48.6)2 - (39.8)2 = ? + 1147.69
$$\frac{28}{65}$$ x $$\frac{195}{308}$$ ÷ $$\frac{39}{44}$$ + $$\frac{5}{26}$$ = ?
[(3$$\sqrt{8}$$+ $$\sqrt{8}$$ ) (8$$\sqrt{8}$$ + 7$$\sqrt{8}$$ )] - 98 = ?
$$\sqrt{11449}$$x$$\sqrt{6241}$$ - (54)2 = $$\sqrt{?}$$ + (74)2
