• C. Logarithms
• D. Fractions

Answer: (B)

Verified step by step guidance

1. Understand that scientific notation is a way to express very large or very small numbers in a compact form.
2. Recognize that scientific notation represents numbers as a product of a number between 1 and 10 and a power of 10.
3. Recall that powers of 10 are expressed using exponents, where the exponent indicates how many times 10 is multiplied or divided.
4. Therefore, the key mathematical concept used in scientific notation is exponents, which simplify the representation by showing repeated multiplication or division by 10.
5. This allows for easier reading, writing, and calculation with extremely large or small numbers.
