Answer:
a. 94,000,000
b. Ninety-four million
Step-by-step explanation:
In order to find this number, move the decimal place to the right by the number in the exponent. Since the exponent is 7, we move it to the right of the 4 (that's one move), then we have six more moves. So we add six zeroes to the end of the number.
