Answer:
4*10^-8
Step-by-step explanation:
1.This is a number smaller than 0, so we will need to shift the decimal point right
2.We write the decimal point after the first non-zero number, followed by the rest of the non-zero digits: 4. This is the base.
3.Next we count how many decimal places we shifted the decimal point
4. Next, we count how many zeroes are in the decimal. There are 8 zeroes so the base will be negative because the number is smaller than 0.
