Write 2.05E+73 in decimal notation.

Step 1: The exponent for 10 is 73. Since the exponent is positive, we must move the decimal point of a number 2.05 73 places to the right.

2.05 → 2.05-----------------------------------------------------------------------.

Step 2: Now we just need to replace empty spaces (dashes) with zeros and to delete old decimal point (the black one) to get:
