Answer 1

All but the last two

Answer 2

Answer:

0.00018 and 1.8 × 10-4

Step-by-step explanation:

Jenna calculated several numbers in her calculator. The result displayed 1.8E-4 on the calculator screen.

1.8E^-4 means there are 3 zeroes after decimal then 18. When a value is very less than zero then the calculator shows that in E form. When we move the decimal to the left, it adds 1 to our exponent.

So, the correct answers are :

0.00018 and 1.8 × 10-4

1.8 × 10-4 = $\frac{1.8}{10000}= 0.00018$
