What I learned this week- Exponents lesson #1

I learned how the exponent laws:

Exponent laws are the rules you follow when you are adding, subtracting, multiplying, or dividing.

The first law is when you are multiplying two numbers with the same base, you add the exponents.

For example: 6^4 x 6^3 = 6^7

The second law is when your dividing two numbers with the same base. You have to divide the exponents.

For example: 6^86^4 = 6^4

The third law is when you are multiplying two numbers by the same exponent. You have to expand out the question then multiply them both by the exponent.

For example:

Then you can expand

You can either leave it like that or keep expanding

6x6x8x8

You do the same with division

When you have two exponents one outside the bracket and one inside the bracket you multiply them.

For example:
