Study Notes

Exponents and Powers

  • 2^4 is equal to 16
  • 3^2 is equivalent to 9
  • (5^2) * (5^3) is equal to 5^5, which is calculated as 5^2 = 25, 5^3 = 125, and then 25 * 125 = 3125
  • (3^4) / (3^2) * (3^3) can be simplified by cancelling out 3^2, resulting in 3^4 * 3 = 3^5, which is equal to 3^5 = 243
  • (4^3) / (4^2) can be simplified by cancelling out 4^2, resulting in 4^1, which is equal to 4
  • (7^4) / (7^4) is equal to 1, as any number raised to the power of 4 divided by the same number raised to the power of 4 is equal to 1
