Question

7^662+9×7^660-8×7^661 ; 2^1651

Answer 1

7662+9(7660)−8(7661)=Infinity+9(7660)−8(7661)=Infinity+(9)(Infinity)−8(7661)=Infinity+Infinity−8(7661)=Infinity−8(7661)=Infinity−(8)(Infinity)=Infinity−Infinity=NaN

Answer 2

7⁶⁶² + 9 * 7⁶⁶⁰ - 8 * 7⁶⁶¹ =
7⁶⁶⁰ (7² + 9 * 7⁰ - 8 * 7¹) = 
7⁶⁶⁰ (49 + 9 * 1 - 56) =
7⁶⁶⁰(49 + 9 - 56) =
7⁶⁶⁰ * 2
7⁶⁶⁰ * 2 > 2¹⁶⁵¹
