6 * 14 - (9 + 8)2 = 50 

First, do the parentheses:

9 + 8 = 17

Your new equation would then be 6 * 14 - 17 * 2

Then multiply starting from left to right:
 
6 * 14 = 84
17 * 2 = 34

Your new equation would then be 84 - 34

Now subtract:

84 - 34 = 50 

There you go! If you have any more questions feel free to comment! :D

Simplify the expression (7 + 9i)(8 - 10i)
NeX [460]

The simplified expression of (7 + 9i)(8 - 10i) is 146 + 2i

<h3>How to simplify the expression?</h3>

The expression is given as:

(7 + 9i)(8 - 10i)

Expand the bracket

7 * 8 + 9i * 8 -7 * 10i - 9i * 10i

Evaluate the products

56 + 72i -70i - 90(i²)

Evaluate the difference

56 + 2i - 90(i²)

In complex numbers;

i² = -1

So, we have:

56 + 2i - 90(-1)

Evaluate

56 + 2i + 90

Add the like terms

146 + 2i

Hence, the simplified expression of (7 + 9i)(8 - 10i) is 146 + 2i

Step-by-step explanation:

company consists of 3 letters followed by 5 numbers how many different account numbers are possible if repetitions of letters and digits are allowed.

We have 26 lettrs and 10 digits

So, the possible out comes for each one of the letters = 26

And the possible out comes for each one of the numbers = 10

∵ repetitions of letters and digits are allowed.

So, the possible accounts are = 26³ * 10⁵ = <u>1,757,600,000</u>
