[ 0.0347 × 0.0347 × 0.0347 + ( 0.9653 )3 ]/[ ( 0.0347 )2 - ( 0.347 × 0.09653 ) + ( 0.9653 )2 ] का मान है

- 0.9306
- 1.0009

- 1
सही विकल्प: D
[ 0.0347 × 0.0347 × 0.0347 + ( 0.9653 )3 ]/[ ( 0.0347 )2 - ( 0.0347 × 0.9653 ) + ( 0.9653 )2 ]
[ ∴ a3 + b3 = ( a + b ) ( a2 + b2 - ab ) ] ( सूत्र )
यहाँ a = 0.0347 तथा b = 0.9653
सूत्र में मान रखने पर
= [ ( 0.0347 )3 + ( 0.9653 )3 ]/[ ( 0.0347 )2 - ( 0.0347 × 0.9653 ) + ( 0.9653 )2 ]
= [ ( 0.0347 + 0.9653 ) ( 0.0347 )2 - ( 0.0347 × 0.9653 ) + ( 0.9653 )2 ]/[ ( 0.0347 )2 - ( 0.0347 × 0.9653 ) + ( 0.9653 )2 ]
= ( 0.0347 + 0.9653 ) = 1
अतः अभीष्ट व्यंजक का मान = 1
