Answer:
hi there!
the correct answer to this question is 7.87 x 10 ^ -1
Step-by-step explanation:
first you want to move the decimal to where the number is between 1-10
then you want to count how many places you moved the decimal:
if the number initially started with 0.00 the exponent will be negative and you insert the number you counted
if the number initially was something like 1234.0 then the exponent will be positive
