Answer:
C 2.35 x 10¹¹
Step-by-step explanation:
You want the number 235,000,000,000 written in scientific notation.
The exponent of 10 when a number is written in scientific notation is the same as the exponent of 10 for the most significant digit when the number is written in expanded form using exponents.
235,000,000,000 = 2×10¹¹ +3×10¹⁰ +5×10⁹ +0×10⁸ +... +0
The place value multiplier for the most-significant digit is 10¹¹, so this is the multiplier when the number is written in scientific notation.
2.35×10¹¹
