Which of the following equals 0.000001 ? \( 1 \times 10^{-6} \) \( 1 \times 10^{-8} \) \( 1 \times 10^{-7} \) \( 1 \times 10^{-5} \)

The notation \( 1 \times 10^{-6} \) represents a number in scientific notation, where the exponent indicates the power of ten by which the number is multiplied. So, \( 1 \times 10^{-6} \) equals 0.000001, because moving the decimal point six places to the left gives us precisely that value! On the other hand, numbers like \( 1 \times 10^{-5} \) represent 0.00001, which is ten times larger than 0.000001, and continuing down the list, \( 1 \times 10^{-7} \) gives you 0.0000001, while \( 1 \times 10^{-8} \) results in 0.00000001. So, when it comes to pinpointing which equals 0.000001, that singular champion is \( 1 \times 10^{-6} \)!
