What students practice

  • Students use integer exponent properties to write equivalent numerical expressions.
  • Students evaluate expressions containing zero and negative integer exponents.
  • Students compare data allowances and costs using equivalent powers.

How to use

Use after teaching integer exponent rules. Have students show their rewrites on separate paper, then discuss how negative exponents affect comparisons.

Check the Calculation Notes

A comparison tool records phone data amounts in equal-sized data blocks. Simplify each expression without a calculator.

1.
The tool records an allowance as 16³ data blocks. Which expression gives the same allowance using base 2?
  • A. 2⁹ data blocks
  • B. 2¹² data blocks
  • C. 2⁷ data blocks
  • D. 2⁴⁸ data blocks
2.
A data adjustment uses the multiplier 10⁰ × 10⁻². Evaluate the multiplier. Write a fraction in simplest form.

Multiplier =  

3.
The tool applies the multiplier (3/7)⁰ to an allowance. What is the value of this multiplier?
  • A. 0
  • B. 1
  • C. 3/7
  • D. 7/3
