Write your answer as a complex number in standard form, i need

10.

11.

Step-by-step explanation:

A complex number is a number made of two parts: a real number and an imaginary number. We write them as a+bi.

We never use i as a variable in math because i is a symbol we use for the square root of -1.  We need to remember how powers of i work because we will be multiplying them and exponents may be possible.

Notice that and both give real number values of -1, and 1. Since we cannot combine real numbers and imaginary numbers with operations like ≠ , we will use exponents of imaginary numbers to convert and properties of algebra to make it possible.

For we will multiply the entire equation by the identity or 1. But we will choose what 1 we use. We choose and multiply.

Notice . We replace it and simplify the integers. Then write it in a+bi order.

We repeat the steps for the second problem.

step-by-step explanation:

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
