*i "***Terms that Use contact Person:**Donna Roberts

When the imaginary unit,

*i*, is increased to increasingly higher powers, a cyclic (repetitive) sample emerges. Remember the

*i*2 = -1.

You are watching: I to the power of 8

*Simplifying strength of **i**:* you will have to remember (or establish) the powers of 1 v 4 that *i* to acquire one cycle of the pattern. From the list that values, girlfriend can conveniently determine any kind of other positive integer strength of *i*.

Method 1: when the exponent is higher than or same to 5, usage the fact that i 4 = 1 and also the rules for working v exponents to simplify greater powers of i. Break the power down to present the determinants of four. when raising i to any type of positive essence power, the prize is always i, -1, -i or 1.Another means to look in ~ the simplification: Method 2: division the exponent by 4: • if the remainder is 0, the price is 1 (i0). • if the remainder is 1, the prize is i (i1). • if the remainder is 2, the prize is -1 (i2). • if the remainder is 3, the price is -i (i3).See more: Nutrition In Living Organisms Need Nutrients In Order To, Do All Living Organisms Need Nutrients |

simplify

*i*87

By Method 1: breakdown the strength to show determinants of 4. (84 is the biggest multiple the 4) |

By Method 2: divide the power by 4 to uncover the remainder. 87 ÷ 4 = 21 through remainder 3 The prize is i3 i m sorry is -i. |

You can raise i to any kind of positive essence value using a TI-84+ calculator. Unfortunately, the older version calculators will only give specific answer ( i, 1, -i, -1) as much as a strength of 6. The more recent TI-84+CE will give precise answer ( i, 1, -i -1) as much as a strength of 100. Past these powers, the calculators will provide an calculation (in clinical notation) that will should be interpreted regarding whether the prize is i, 1, -i , or -1. check out more. |
