Perform the indicated operation and express the result as a simplified complex number. I need help with 35
skelet666 [1.2K]

Given:-

\frac{3+4i}{2-i}

To find:-

The simplified form.

At first we take conjucate and multiply below and above.

The conjucate is,

2+i

So now we multiply. we get,

\frac{3+4i}{2-i}\times\frac{2+i}{2+i}

Now we simplify. so we get,

\frac{3+4i}{2-i}\times\frac{2+i}{2+i}=\frac{6+3i+8i+4(i)^2}{2^2-i^2}

We know the value of,

i^2=-1

Substituting the value -1. we get,

\begin{gathered} \frac{6+3i+8i+4(i)^2}{2^2-i^2}=\frac{6+3i+8i+4(-1)_{}^{}}{2^2-(-1)^{}} \\ \text{                               =}\frac{6-4+11i}{2+1} \\ \text{                              =}\frac{2+11i}{3} \end{gathered}

So now we split the term to bring it into the form a+ib. so we get,

\frac{2+11i}{3}=\frac{2}{3}+i\frac{11}{3}

So the required solution is,

\frac{2}{3}+i\frac{11}{3}

Which identity could be used to rewrite the expression x^4-100?
zzz [600]
Given the polynomial of degree 4, this can be written as:
x^4-100
let
x^2=a
thus the expression can be written as:
a^2-100
this is a polynomial of degree 2 also known as quadratic equation.
Hence the answer is:

3(x + 1) + 2 &lt; 11<br> Solve each inequality and graph the solution
maxonik [38]

Answer:

3x+3+2<11

Step-by-step explanation:

3x<11+3+2

3x<16

so now you divide 3 by the co-efficient

3x/3<16/3

so now 3 council 3 then you get x

x<16/3

x<5

now x is equal to 5
