is there a easier way of doing a very long exponents ?

You can use the associative property of multiplication to group numbers. For example: 3^6 = 3 x 3 x 3 x 3 x 3 x 3 If you do in one at a time: 3 x 3 = 9; 9 x 3 = 27; 27 x 3 = 81; 81 x 3 = 243; 243 x 3 = 729 Using grouping: (3 x 3) x (3 x 3) x (3 x 3) = 9 x 9 x 9 = 81 x 9 = 729 Hope this helps.

how do I express 144 in exponential form?

12^2 is the same as 12 * 12, or 144.

im wrighting notes on my laptop but i cant figure out how to right it as 4 to the 3rd power with out completely typing a sentence out every time i use open office its the same thing basically as microsoft office

for me you hold shift and press 6 so it would be 4^3

why do we use exponents?

Hey Aaron, exponents are just a faster (and easier) way to show repeated multiplication.

how are you supposed to write an exponent when your keyboard doesn't do that

Use the carat symbol "^" (shift-6) on your keyboard. For example: 5^3 is understood to be 5 to the power of 3. Hope this helps.

Do we have to watch the videos even if we know the answer and we understand exsponets

no but it will still give you points if you play the vid and walk away

Lesson 1: Meaning of exponents

Intro to exponents

Google Classroom

Learn how to use exponents and bases. For example, writing 4 x 4 x 4 x 4 x 4 with an exponent.

Here's what an exponent and a base look like:

$4^{3}$ ‍

The small number written above and to the right of a number is called an

exponent

. The number underneath the exponent is called the

base

. In this example, the base is

4

, and the exponent is

3

Here's an example where the base is

7

, and the exponent is

5

$7^{5}$ ‍

An exponent tells us to multiply the base by itself that number of times. In our example,

4^{3}

tells us to multiply the base of

4

by itself

3

times:

$4^{3} = 4 \times 4 \times 4$ ‍

Once we write out the multiplication problem, we can easily evaluate the expression. Let's do this for the example we've been working with:

$4^{3} = 4 \times 4 \times 4$ ‍

$= 16 \times 4$ ‍

$= 64$ ‍

The main reason we use exponents is because it's a shorter way to write out big numbers. For example, let's say we want to express the following:

$2 \times 2 \times 2 \times 2 \times 2 \times 2$ ‍

That's really long to write. My hands hurt just from typing it! Instead we can see that

2

is multiplied by itself

6

times. This means we can write the same thing with

2

as the base and

6

as the exponent:

$2 \times 2 \times 2 \times 2 \times 2 \times 2 = 2^{6}$ ‍

Cool, lets make sure we understand exponents by trying some practice problems.

Practice set:

Problem 1A

Write $7 \times 7 \times 7$ ‍ using an exponent.

Challenge set:

Problem 2A

Complete the inequality with $>, <,$ ‍ or $=$ ‍.

2^{5}

5^{2}

  You can use the associative property of multiplication to group numbers.
  For example:
  3^6 = 3 x 3 x 3 x 3 x 3 x 3
  If you do in one at a time: 3 x 3 = 9; 9 x 3 = 27; 27 x 3 = 81; 81 x 3 = 243; 243 x 3 = 729
  Using grouping: (3 x 3) x (3 x 3) x (3 x 3) = 9 x 9 x 9 = 81 x 9 = 729
  
  Hope this helps.
