1.	√1224 × 12.06 + √4897 - (18.98)2 = ?1). 1202). 1103). 1254). 129
Answer» Follow BODMAS rule to solve this question, as per the order given below, Step-1 - PARTS of an equation ENCLOSED in 'Brackets' must be SOLVED first, and in the bracket, Step-2 - Any mathematical 'Of' or 'Exponent' must be solved next, Step-3 - Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated, Step-4 - Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated. Given expression is, √1224 × 12.06 + √4897 - (18.98)² = ? Taking Approximate values as, √1224 ≈ √1225, 12.06 ≈ 12, √4897 ≈ √4900, (18.98)² ≈ (19)² ⇒ √1225 × 12 + √4900 - (19)² = ? ⇒ 35 × 12 + 70 - 361 = ? ∴ ? = 129

Answer»

Follow BODMAS rule to solve this question, as per the order given below,

Step-1 - PARTS of an equation ENCLOSED in 'Brackets' must be SOLVED first, and in the bracket,

Step-2 - Any mathematical 'Of' or 'Exponent' must be solved next,

Step-3 - Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step-4 - Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

Given expression is,

√1224 × 12.06 + √4897 - (18.98)² = ?

Taking Approximate values as,

√1224 ≈ √1225, 12.06 ≈ 12, √4897 ≈ √4900, (18.98)² ≈ (19)²

⇒ √1225 × 12 + √4900 - (19)² = ?

⇒ 35 × 12 + 70 - 361 = ?

∴ ? = 129
