Write this number in standard notation. 1.986 x 10negative exponent 6 or 1.986 x 10^6

Brums [2.3K]

Answer:

$0.000001986$

Explanation:

We have the number $1.986*10^{-6}$ . Standard notation would basically be this number without the $10^{-6}$ part.

To get rid of this part, we need to move the decimal point 6 places to the left (we go left because it's negative 6, indicating division).

So, when we move the decimal point 6 places to the left, the resulting number is: $0.000001986$ , with 5 zeros after the decimal point before a nonzero number.

Thus, the answer is $0.000001986$ .
