<span>3/4x - 4/5 = 1/2x + 1

</span>3/4x - 4/5 = 2/4x + 1

3/4x - 2/4x = 1 + 4/5

1/4x = 9/5

x = (9x4) / (5x1)

x = 36/5

x = 7 1/5

What is the value of i 97 – i?<br> –i<br> 0<br> –2i<br> i Superscript 96

Valentin [98]

<em>The question is not clearly readable, but I'm assuming the expression which makes more sense, so you can have a clue</em>

Answer:

$i^{97}-i=0$

Step-by-step explanation:

<u>Powers of The Imaginary Unit</u>

The imaginary unit i is defined as

$i=\sqrt{-1}$

The first powers of i are

$i^0=1$

$i^1=i$

$i^2=(\sqrt{-1})^2=-1$

$i^3=i.i^2=-i$

$i^4=i^2.i^2=1$

And so on the cycle repeats every four numbers. To find the value of $i^{96}$ we can find the remainder of 96/4=0. So $i^{96}=i^0=1$

The given expression is

$i^{97}-i$

Factoring

$i(i^{96}-1)$

Since $i^{96}=1$

$=i(1-1)=0$

The required value is 0
