Powers of Ten Worksheet (printable, online, answers) - Free Printable

Let’s solve this step by step.

We’re working with powers of 10. That means we multiply 10 by itself a certain number of times, based on the exponent (the small number up top).

For example:
10² = 10 × 10 = 100
10³ = 10 × 10 × 10 = 1,000

A quick trick: The exponent tells you how many zeros are in the answer!
So 10⁵ = 1 followed by 5 zeros → 100,000

Part 1: Find the values

a. 10³ = 10 × 10 × 10 = 1,000
b. 10⁵ = 1 followed by 5 zeros → 100,000
c. 10⁶ = 1 followed by 6 zeros → 1,000,000
d. 10⁴ = 1 followed by 4 zeros → 10,000
e. 10¹ = just 10 (only one zero)
f. 10⁷ = 1 followed by 7 zeros → 10,000,000
g. 10² = 10 × 10 = 100
h. 10⁹ = 1 followed by 9 zeros → 1,000,000,000
i. 10⁸ = 1 followed by 8 zeros → 100,000,000
j. 10¹⁰ = 1 followed by 10 zeros → 10,000,000,000

Part 2: Write in exponential form

This is the reverse — count the zeros and that’s your exponent!

a. 10,000 → has 4 zeros → 10⁴
b. 1,000 → has 3 zeros → 10³
c. 10 × 10 = 100 → which is 10² → 10²
d. 100 × 100 = 10,000 → 4 zeros → 10⁴
e. 1,000,000 → 6 zeros → 10⁶
f. 1,000 × 1,000 = 1,000,000 → 6 zeros → 10⁶
g. 100 → 2 zeros → 10²
h. 1 × 10 = 10 → 1 zero → 10¹
i. 100,000 → 5 zeros → 10⁵
j. 100 × 10 = 1,000 → 3 zeros → 10³
k. 100,000 → same as i → 10⁵
l. 10,000 × 10 = 100,000 → 5 zeros → 10⁵

Wait — let me double-check part f and k and l to be sure:

f. 1,000 × 1,000 = 1 million → yes, 10⁶ ✔️
k. 100,000 → definitely 10⁵ ✔️
l. 10,000 × 10 = 100,000 → yes, 10⁵ ✔️

Also check c: 10 × 10 = 100 = 10² ✔️
d: 100 × 100 = 10,000 = 10⁴ ✔️
h: 1 × 10 = 10 = 10¹ ✔️

All good!
