C) (4 × 10¹0)
D) (8 × 10¹1)

Answer 1

To write (2³⁰) in standard form correct to 1 significant figure, the answer is (2 × 10³⁰).

Step-by-step explanation:

To write (2³⁰) in standard form correct to 1 significant figure, we need to convert it into scientific notation. The rule for expressing a number in scientific notation is to multiply a number between 1 and 10 with a power of 10. In this case, we have 2³⁰, so we can write it as 2 × 10³⁰. However, since we need to round to 1 significant figure, the final answer is (2 × 10³⁰).
