Question

(0.98) whole square evaluate it

Answer 1

Hey mate!!!!

Using (a -b)² = a² + b² -2ab
$(0.98) {}^{2} \\ = (1 - 0.02) {}^{2} \\ = {1}^{2} + 0.02 {}^{2} - 2 \times 1 \times 0.02 \\ = 1 + 0.0004 - 0.04 \\ = 1.0004 - 0.04 \\ = 0.9604$
hope it helps dear friend ☺️✌️✌️

Answer 2

Hi there

Your answer is :-

(0.98)^2

(98/100)^2

(49/50)^2

49x49/50×50

2401/2500


Hence another form = 0.9604


Thank You
