Answer 1

Explanation:

To express the number 1.201 × 10^-7 in decimal form, we need to multiply the number 1.201 by 10 raised to the power of -7.

10 raised to the power of -7 is equal to 0.0000001 (seven decimal places to the right of the decimal point).

When we multiply 1.201 by 0.0000001, we move the decimal point seven places to the left:

1.201 × 0.0000001 = 0.0000001201

Therefore, the correct decimal representation of the number 1.201 × 10^-7 is 0.0000001201.

In summary, the correct answer is C) 0.0000001201.
