Step-by-step explanation:
The student's question is asking to express the value of the electronic coin, empower (EMPR), worth $4.77E-9 in decimal notation. The correct answer is: a) $0.00000000477. This is because scientific notation is expressed in the form of a number between 1 and 10 multiplied by a power of 10. For instance, the amount $79.2 billion can be written in scientific notation as $7.92 × 10¹°. Similarly, expressing smaller quantities like electronic coin values or atomic charges can be represented in scientific notation before converting back to standard decimal form.
