The negative index of $10$ indicates that you are dividing by 10, twice:

$9.01 xx 10^-2 = 9.01 div 10 div 10$

$= 0.0901$

OR

You can write this as a fraction:

$9.01 xx 10^-2 = 9.01 xx 1/10^2 = 9.01 xx1/100$

$=0.0901$

OR

You can simply apply the rule which says move the decimal point to the left by $2$ places.

$9.01 xx10^-2 = 0.0901$
