Question

When 29011 is written in scientific notation, the exponent indicating the power of 10 is:

A) 4
B) 5
C) 6
D) 7

Answer 1

The number 29011 can be expressed in scientific notation as 2.9011 × 10 to the fourth power, with the exponent indicating the power of 10 being 4.

Step-by-step explanation:

To express the number 29011 in scientific notation, we follow the rule of placing a decimal point after the first nonzero digit, then counting how many places the decimal point moves from its original position at the end of the number to its new position. For 29011, the first nonzero digit is 2, so we write it as 2.9011. Then we count the places we move the decimal point; in this case, we move it 4 places to the left to get the number between 1 and 10. Therefore, 29011 can be expressed as 2.9011 × 104. The exponent indicating the power of 10 is thus 4.
