Answer;
3.45 × 10^-1
Explanation;
-Here we wish to write the number 0.345 as a coefficient times 10 raised to an exponent. To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45.
-The number of places to the left that you had to move the decimal point is the exponent.
= 0.345
= 3.45/10
= 3.45 × 10^-1
