Final answer:
The sum of (2.6 x 10) and (9.2 x 10) is 118, which in scientific notation is 1.18 x 10^2. None of the provided options correctly represents this value in scientific notation.
Step-by-step explanation:
The student asked for the sum of (2.6 x 10) and (9.2 x 10) expressed in scientific notation. To solve this, we first calculate the sum of 2.6 x 10 and 9.2 x 10, which gives us 26 + 92 = 118. Now, we'll express 118 in scientific notation. The correct scientific notation for 118 is 1.18 x 102. Therefore, the answer, expressed in proper scientific notation, is not a) 118x10-10, b) 1.18x109, or d) 1.18x108, but closely related to c) 118x107. However, none of the options provided is exactly right because the correct scientific notation of 118 is 1.18 x 102. Among the options, the most similar structure is 1.18x107, but 'c' erroneously states 118 instead of 1.18, and 107 instead of 102.
