Answer 1

The number 2.9×107 is equivalent to 29,000,000 when converted from scientific notation to standard form by moving the decimal point 7 places to the right.

Step-by-step explanation:

The number 2.9×107 is equivalent to 29,000,000 (option c). In scientific notation, a number is written as the product of a number between 1 and 10 and a power of 10. Here, 2.9 represents the digit term, and 107 (10 raised to the power of 7) indicates where the decimal point should be moved. To convert from scientific notation to standard form, you move the decimal point 7 places to the right, which gives us 29,000,000.
