1.1 ×10
Explanation: when you divide it it comes to .0011
and with significant figures you move the decimal over until it is right after the first number that is not zero. so that would change .0011 to 1.1
also with significant figures if you move the decimal to the right you exponent by the 10 will be negative and if you move it to the left it will be positive. so I. this case we are moving g to the right 3 digits so our exponent will be negative 3.
and because the answer is still really. 0011 you multiply
-3
1.1 × 10
