If a= ₂ 3, b= ₂ 5, c= ₇ 2 , then ₁₄₀ 63 in terms of a, b, c is
Options
- A2 a c+1 2 a+a b c+1
- B2 a c+1 2 a+c+a
- C2 a c+1 2 c+a b+a
- DNone of these
Correct answer
D. None of these
Step-by-step solution
Now, ₁₄₀ 63= _ 2^2 5 7 (3 3 7) aligned & = ₂(3 3 7) ₂ (2^2 5 7 ) = ₂ 3+ ₂ 3+ ₂ 7 2 ₂ 2+ ₂ 5+ ₂ 7 & = 2 a+ 1 c 2+b+ 1 c = 2 a c+1 2 c+b c+1 aligned
