Hint – To simplify the equation given in the question we use the algebraic formula ( – ) and solve for answer.
Complete step-by-step answer:
Given Data,
0.54x0.54 – 0.46x0.46 =
Now, Let a = 0.54 and b = 0.46
⟹ = ( – )
= (a + b) × (a – b)
= (0.54 + 0.46) × (0.54 – 0.46)
= 1x 0.08
= 0.08
Hence Option C is the correct answer.
Note – In order to solve this type of questions the key is to identify if the given equation fits into a known algebraic formula, if not we reduce it in such a way that it transforms into a known formula. Basic knowledge in algebraic formulae is required.
