Powers of 10 & Exponents (Mixed Review) — Easy Worksheet 1
Grade 5 · Whoobee Name: ____________________ Date: __________
Find each missing number. Write decimals without extra zeros.
How to solve
The exponent tells how many times 10 is used as a factor, so 103 = 10 × 10 × 10 = 1,000 (a 1 followed by 3 zeros). Multiplying by 103 moves every digit 3 places to the left (the decimal point moves right); dividing by 103 moves every digit 3 places to the right (the decimal point moves left).
Example
104 = ___
Answer: 10000
Not quite. The answer is
💡 100 is a 1 followed by 2 zeros, so it is 2 tens multiplied together: 102. The exponent is 2.
✓ Correct!
