Download Solution PDFপ্রদত্ত সমীকরণ: 450 * 300 * √144 * 162 * 489 * 411
আসুন BODMAS নিয়ম ব্যবহার করে প্রতিটি বিকল্প পরীক্ষা করি,
1) +, =, -, +, -
450 + 300 = √144 - 162 + 489 - 411
750 = 12 - 162 + 78
750 = -72
LHS ≠ RHS
2) -, x, =, +, +
450 - 300 x √144 = 162 + 489 + 411
150 x 12 = 1062
1800 = 1062
LHS ≠ RHS
3) =, x, +, -, +
450 = 300 x √144 + 162 - 489 + 411
450 = 300 x 12 + 84
450 = 3600 + 84
450 = 3684
LHS ≠ RHS
4) +, -, +, =, +
450 + 300 - √144 + 162 = 489 + 411
750 - 12 + 162 = 900
738 + 162 = 900
900 = 900
LHS = RHS.
এখানে, আমরা দেখতে পাচ্ছি যে বিকল্প 4 সমীকরণটিকে সন্তুষ্ট করে।
সুতরাং, সঠিক উত্তর হল "+, -, +, =, +"।
