Math Problem Statement

Order the expressions by choosing >, <, or =: 1. 2^3 × 2^2 and 2^6, 2. 2^2 × 3^2 and 6^3, 3. 2^3 × 3^2 and 6^2.

Solution

Let's break down the expressions and compare them step by step.

Expressions:

  1. 23×222^3 \times 2^2 on the left, 262^6 on the right.
  2. 22×322^2 \times 3^2 on the left, 636^3 on the right.
  3. 23×322^3 \times 3^2 on the left, 626^2 on the right.

Simplification:

  1. First expression: 23×22=23+2=252^3 \times 2^2 = 2^{3+2} = 2^5 Compare with 262^6: 25<262^5 < 2^6 So, the first comparison is less than ( < ).

  2. Second expression: 22×32=4×9=362^2 \times 3^2 = 4 \times 9 = 36 Compare with 63=6×6×6=2166^3 = 6 \times 6 \times 6 = 216: 36<21636 < 216 So, the second comparison is also less than ( < ).

  3. Third expression: 23×32=8×9=722^3 \times 3^2 = 8 \times 9 = 72 Compare with 62=6×6=366^2 = 6 \times 6 = 36: 72>3672 > 36 So, the third comparison is greater than ( > ).

Final Order:

  1. 23×22<262^3 \times 2^2 < 2^6
  2. 22×32<632^2 \times 3^2 < 6^3
  3. 23×32>622^3 \times 3^2 > 6^2
