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

When the imagine unit,

*i*, is raised to increasingly higher powers, a cyclic (repetitive) pattern emerges. Remember that

*i*2 = -1.

You are watching: I to the power of 9

*Simplifying powers of **i**:* friend will need to remember (or establish) the powers of 1 with 4 that *i* to achieve one bike of the pattern. From the list the values, girlfriend can easily determine any type of other confident integer strength of *i*.

Method 1: once the exponent is better than or same to 5, use the reality that i 4 = 1 and the rules because that working v exponents come simplify greater powers of i. Break the power down to show the determinants of four. when raising i to any kind of positive creature power, the answer is constantly i, -1, -i or 1.Another way to look at the simplification: Method 2: division the exponent through 4: • if the remainder is 0, the prize is 1 (i0). • if the remainder is 1, the answer is i (i1). • if the remainder is 2, the prize is -1 (i2). • if the remainder is 3, the answer is -i (i3).See more: 10,000,000 Yen To Usd ) - 1 Million Japanese Yen To Us Dollar |

*i*87

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

By Method 2: divide the strength by 4 to uncover the remainder. 87 ÷ 4 = 21 with remainder 3 The price is i3 i beg your pardon is -i. |

You deserve to raise i to any positive integer value making use of a TI-84+ calculator. Unfortunately, the older version calculators will only give precise answer ( i, 1, -i, -1) up to a power of 6. The more recent TI-84+CE will certainly give an exact answer ( i, 1, -i -1) as much as a strength of 100. Past these powers, the calculators will give an estimate (in scientific notation) the will have to be interpreted as to whether the prize is i, 1, -i , or -1. read more. |
