Math Problem Statement

Order the expressions by choosing >, <, or =: 1. 2^2 × 3 vs. 6^2, 2. 2^3 × 3^2 vs. 6^2, 3. 2^5 × 3 vs. 6^3.

Solution

The question asks to order three mathematical expressions using either the symbols >>, <<, or ==.

The expressions involve exponents:

  1. 22×32^2 \times 3 vs. 626^2
  2. 23×322^3 \times 3^2 vs. 626^2
  3. 25×32^5 \times 3 vs. 636^3

Let’s calculate each side for comparison:

1. 22×32^2 \times 3 vs. 626^2

  • 22=42^2 = 4
  • 4×3=124 \times 3 = 12
  • 62=366^2 = 36

So, 12<3612 < 36.

2. 23×322^3 \times 3^2 vs. 626^2

  • 23=82^3 = 8
  • 32=93^2 = 9
  • 8×9=728 \times 9 = 72
  • 62=366^2 = 36

So, 72>3672 > 36.

3. 25×32^5 \times 3 vs. 636^3

  • 25=322^5 = 32
  • 32×3=9632 \times 3 = 96
  • 63=2166^3 = 216

So, 96<21696 < 216.

Final Order:

  • 22×3<622^2 \times 3 < 6^2
  • 23×32>622^3 \times 3^2 > 6^2
  • 25×3<632^5 \times 3 < 6^3

You can use the symbols <,>,<<, >, < in the correct order.

Would you like more details or have any questions? Here are some related questions:

  1. How do we simplify expressions with exponents?
  2. Why does 23×322^3 \times 3^2 result in a value greater than 626^2?
  3. What is the general rule for comparing powers of different numbers?
  4. How does multiplying bases affect the result compared to raising the base to a power?
  5. Can exponents always be compared directly?

Tip: When comparing exponential expressions, simplify both sides to numerical values for direct comparison.
