Q. Which exponential expression is equivalent to k ?Choose 1 answer:(A) k21(B) k211(C) k2(D) k21
Identify exponential form: Identify the exponential form of a square root.The square root of k, denoted as k, can be written in exponential form as k raised to the power of 21.
Match with given choices: Match the exponential form with the given choices.The exponential form of k is k(1/2), so we need to find this expression among the choices provided.
Eliminate incorrect choices: Eliminate incorrect choices.(A) (1)/(k2) is the reciprocal of k squared, not the square root of k.(B) (1)/(k(1)/(2)) is the reciprocal of the square root of k, not the square root itself.(C) k2 is k squared, not the square root of k.(D) k(1)/(2) is the correct exponential form of the square root of k.
Choose correct answer: Choose the correct answer.The correct exponential expression equivalent to k is (D) k(21).
