Solve for the Missing Power in Equations
Written by Adi Ackerman, Head Teacher
"Solve for the Missing Power in Equations" is written for 8th Grade (Ages 13-14), and it covers Common Core 8.EE.A.1. A 7th grader who is already steady on exponents can use it too, and an older student can use it as a short review.


8th grade math worksheet: rewrite equations like 8² = 2 to the x with one base, then set the exponents equal to solve. Answer key included. Part of our properties of exponents collection. Aligned to Common Core standards.
How do I use this worksheet?
Start with the three single rule sheets and keep the reference sheet nearby. Use the matching and true or false sheets to surface mistakes, then finish with a puzzle for review.
What students will practice
- Students will rewrite numbers such as 9, 27 and 1/8 as powers of a common base.
- Students will set exponents equal once both sides share the same base.
- Students will solve for an unknown exponent x in each equation.

FAQ
How do I use this properties of exponents worksheet?
⌄
Start with the three single rule sheets and keep the reference sheet nearby. Use the matching and true or false sheets to surface mistakes, then finish with a puzzle for review.
What does this worksheet teach?
⌄
Rewrite equations like 8² = 2 to the x with one base, then set the exponents equal to solve. The directions on the page read: Rewrite each equation so both sides are powers of the same base, and write it on the Same base line. Then set the exponents equal and write the value of x. An answer key is included.
Can I use this properties of exponents worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 8th grade exponents, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What is the product of powers rule?
⌄
To multiply powers with the same base, keep the base and add the exponents. So 3⁴ × 3² = 3⁶. Product of Powers With Integer Bases also includes negative bases such as (−2)³ × (−2)⁴.
What is the power of a power rule?
⌄
To raise a power to another power, keep the base and multiply the exponents, so (5²)³ = 5⁶. A common mistake is adding the exponents instead, which True or False, Exponent Property Statements asks students to catch.
How do you find a missing exponent?
⌄
Work the rule backward. In 5³ × 5 to the ? = 5⁹, the exponents must add to 9, so the missing exponent is 6. Two sheets practice this with numeric bases and with variable bases such as x and y.
Is there an exponent rules cheat sheet?
⌄
Yes. The Properties of Exponents Reference Sheet lists each rule with its form, a plain explanation and a worked example. It is a handout, so it has no answer key.
