  1. so welcome back to algebra once again, eighth grade.
  2. Today we're going to be doing exponents.
  3. Um, and exponents can be called the index or a
  4. power. The base number in size is always larger than
  5. makes phone it.
  6. So we're going to learn how to solve one and
  7. simplify and exponents or index or power of a number
  8. says how many times to use that number in a
  9. multiplication. It is written as a small number to the
  10. right and above the base number.
  11. So here we have eight as our base number and
  12. to as our exponents.
  13. So in this example, eight to the second power is
  14. equal to eight times eight, which is simply 64.
  15. He exploded to says, to use the 82 times and
  16. the multiplication.
  17. So we're going to get the base number, which is
  18. eight, and multiply twice because the exponents is to telling
  19. us to multiply two times.
  20. Our first example is fifth to third power Well, five
  21. to third power either way.
  22. So they are exponents, which is three is telling us
  23. to multiply the 53 times so five times five times
  24. five, which is going to give us 125.
  25. The 125 is our simplified version.
  26. The exponents three says to use the 53 times in
  27. a multiplication example number two to to the fourth power,
  28. which equals two types two times two types to which
  29. equals 16.
  30. So are four, which is our exponents on the top
  31. is telling us to multiply 24 times in words to
  32. with the small for the top could be called called
  33. to to the fourth power or to to the power
  34. of four or simply to to the fourth.
  35. Great job we have finished simplifying exponents.
  36. Hopefully you have learned how to simplify and solve and
  37. exponents please visit my website hips slash slash sites dot
