Question
Write 7.29E-23 in decimal notation.
Answer
7.29E-23 = 0.0000000000000000000000729
Explanation
Step 1: The exponent for 10 is -23. Since the exponent is negative, we must move the decimal point of a number 7.29 23 places to the left.
7.29 → .----------------------7.29
Step 2: Now we just need to replace empty spaces (dashes) with zeros and to delete old decimal point (the black one) to get:
.0000000000000000000000729
