Answer:

4+6i-6i^2+3i^3-4i^4=6+3i

Step-by-step explanation:

Given the expression

4+6i-6i^2+3i^3-4i^4

as

i^2=-1\\

so

=4+6i-\left(-6\right)-3i-4i^4

Group like terms

=-4i^4+6i-3i+4+6

Add similar items

=-4i^4+3i+4+6

Add the numbers

=-4i^4+3i+10

=6+3i

Thus,

4+6i-6i^2+3i^3-4i^4=6+3i

Answer:

The answers are below

Step-by-step explanation:

The greater sign is > and the less then symbol is <

Using the red arrows on the number line, you can tell which one is bigger or less. The dot is colored in so it has to have a line under it. So for the first one (top, left), The red arrow is pointing to the right side meaning x is bigger than 3. Therefore x ≥ 3.

In the next one (top, right) the arrow is pointing to the negative side so that one must be less than 3. The dot is also colored in meaning it is: x ≤ 3

In the next one (bottom, left) the arrow is pointing to the right, the dot not colored in, so it has no line. Therefore it is  x > 3

Last one (bottom right) the arrow is pointing left, dot is white meaning that the answer is x < 3

If you're wondering what the open dots and closed dots mean:

An open dot is used to show that the ray's endpoint is not a component of the solution when the inequality is "strict" ( < or >).

A closed dot is used to denote that the endpoint is a component of the solution for the other types of inequalities (≥ and ≤ ).
