At the age of 16, “voices” of Christian saints told Joan to aid Charles, the French dauphin, in gaining the French throne and expelling the English from France. Convinced of the validity of her divine mission, Charles furnished Joan with a small force of troops
Answer:
(a) [ (-4) ÷ 2 ] < [ (-16) ÷ 4 ] ÷ (-2)
Explanation:
a) [ (-4) ÷ 2 ] < [ (-16) ÷ 4 ] ÷ (-2)
i)=》[ (-4) ÷ 2 ]
=》-2
ii)=》[ (-16) ÷ 4 ] ÷ (-2)
=》 [-4] ÷ (-2)
=》 2
So, -2 < 2. Correct.
b) [ (-16) ÷ (-4) ] = [ (-8) ÷ 4 ]
i) =》[ (-16) ÷ (-4) ]
=》4
ii)=》[ (-8) ÷ 4 ]
=》-2
So, 4 = -2. Wrong
c) (-16) ÷ 4 ] ÷ (-2) > (-16) ÷ [ 4 ÷ (-2) ]
i) =》 [ (-16) ÷ 4 ] ÷ (-2)
=》 -4÷(-2)
=》 2
ii) =》 (-16) ÷ [ 4 ÷ (-2) ]
=》(-16) ÷ [-2]
=》 8
So, 2 > 8. Wrong
d) (-16) ÷ [ 4 ÷ (-2) ] < [ (-16) ÷ 4 ] ÷ (-2)
i)=》 (-16) ÷ [ 4 ÷ (-2) ]
=》 (-16)÷ [-2]
=》 8
ii)=》[ (-16) ÷ 4 ] ÷ (-2)
=》[-4] ÷ (-2)
=》 2
So, 8 < 2. Wrong.
Hence, the correct option is (a) [ (-4) ÷ 2 ] < [ (-16) ÷ 4 ] ÷ (-2)
