$1.54 \times 10^{- 10}$ $1.54xx10^{-10}$ .

Explanation:

Move the decimal point until you have one nonzero digit to the left of it. The number with the decimal point moved is $a$ $a$ , the number of places you moved the decimal point is $n$ $n$ , and then you have

$a \times 10^{n}$ $axx10^{n}$ if you moved the decimal point to the left

$a \times 10^{- n}$ $axx10^{-n}$ if you moved the decimal point to the right

$a \times 10^{0}$ $axx10^{0}$ , because $n = 0$ $n=0$ , if you did not have to move the decimal point
