Write 2E-179 in decimal notation.

Step 1: Since 2 do not have a decimal point, we will add one at the end of the number 2.

2.

Step 2: The exponent for 10 is -179. Since the exponent is negative, we must move the decimal point of a number 2. 179 places to the left.

2. → .----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------2.

Step 3: Now we just need to replace empty spaces (dashes) with zeros and to delete old decimal point (the black one) to get:
