Answer» $(\frac{{{{\LEFT( {94.975} \RIGHT)}^2} - \;{{\left( {44.995} \right)}^2}}}{{49.95\; \TIMES \;34.98}} = ?)$ Take approximated values ⇒ 94.975 ≈ 95 ⇒ 44.995 ≈ 45 ⇒ 49.95 ≈ 50 ⇒ 34.98 ≈ 35 Putting these values in the equation $(\Rightarrow {\rm{}}\frac{{{{\left( {95} \right)}^2} - \;{{\left( {45} \right)}^2}}}{{50\; \times \;35}})$ ⇒ (95)2 – (45)2 = (95 – 45) × (95 + 45) [? a2 – B2 = (a + b)(a – b)] $(\Rightarrow {\rm{}}\frac{{\left( {95{\rm{\;}}-{\rm{\;}}45} \right){\rm{\;}} \times {\rm{\;}}\left( {95{\rm{\;}} + {\rm{\;}}45} \right)}}{{50\; \times \;35}}{\rm{}} = {\rm{}}\frac{{50{\rm{\;}} \times {\rm{\;}}140}}{{\left( {50{\rm{\;}} \times {\rm{\;}}35} \right)}}{\rm{}} = {\rm{}}4)$ ∴ ? = 4 |
