Answer» Correct option is (C) 29 \((\frac{1}{2})^{-2}+(\frac{1}{3})^{-2}+(\frac{1}{4})^{-2}\) \(=(2^{-1})^{-2}+(3^{-1})^{-2}+(4^{-1})^{-2}\) \(=2^2+3^2+4^2\) = 4+9+16 = 29 Correct option is C) 29

\((\frac{1}{2})^{-2}+(\frac{1}{3})^{-2} \, +(\frac{1}{4})^{-2} = ...................\)(1/2)-2 + (1/3)-2 +(1/4)-2 = .............A) 16 B) 19C) 29 D) 32

Answer»

Correct option is (C) 29

\((\frac{1}{2})^{-2}+(\frac{1}{3})^{-2}+(\frac{1}{4})^{-2}\) \(=(2^{-1})^{-2}+(3^{-1})^{-2}+(4^{-1})^{-2}\)

\(=2^2+3^2+4^2\)

= 4+9+16 = 29

Correct option is C) 29
