Answer 1

Answer:

Correct option is

Correct option isD

Correct option isD[19−15−2564]

Correct option isD[19−15−2564]Given,

Correct option isD[19−15−2564]Given,A=(253−7)

Correct option isD[19−15−2564]Given,A=(253−7)⇒A′=(235−7)

Correct option isD[19−15−2564]Given,A=(253−7)⇒A′=(235−7)Now,(A′)2

Correct option isD[19−15−2564]Given,A=(253−7)⇒A′=(235−7)Now,(A′)2=(235−7)2

Correct option isD[19−15−2564]Given,A=(253−7)⇒A′=(235−7)Now,(A′)2=(235−7)2=(235−7)(235−7)

Correct option isD[19−15−2564]Given,A=(253−7)⇒A′=(235−7)Now,(A′)2=(235−7)2=(235−7)(235−7)=(2⋅2+5⋅33⋅2+(−7)⋅32⋅5+5(−7)3⋅5+(−7)(−7))

Correct option isD[19−15−2564]Given,A=(253−7)⇒A′=(235−7)Now,(A′)2=(235−7)2=(235−7)(235−7)=(2⋅2+5⋅33⋅2+(−7)⋅32⋅5+5(−7)3⋅5+(−7)(−7))=(19−15−2564)
