Q. Which exponential expression is equivalent to k?Choose 1 answer:(A) k21(B) k211(C) k2(D) k21
Understand the problem: Understand the problem.We need to find the exponential expression equivalent to the square root of k, which is written as k.
Express in exponential form: Express the square root in exponential form.The square root of a number can be expressed as that number raised to the power of 21. Therefore, k is equivalent to k21.
Match with given options: Match the expression with the given options.We compare k1/2 with the given options to find the equivalent expression.(A) (1)/(k2) is not equivalent because it represents the reciprocal of k squared.(B) (1)/(k(1)/(2)) is not equivalent because it represents the reciprocal of the square root of k.(C) k2 is not equivalent because it represents k squared.(D) k(1)/(2) is equivalent because it represents the square root of k.
Choose correct answer: Choose the correct answer.The correct answer is (D) k(21), which is equivalent to k.
