How do we use the laws of exponents?

The zero power Anything to the power of zero is one

You try 4 0 =1 X 0 =1 4905 0 =?

Multiply with same base number If you are multiplying and the base number is the same then you add the exponents (x 4 )(x 6 )=x 10 (5 6 )(5 8 )=5 14

You try (3 4 )(3 10 ) (y 5 )(y 7 )

Dividing with the same base number If you are dividing and the base number is the same them you subtract T 7 =T 2 T 5 5 10 =5 1 5 9

You try W 6 =? W 4 4 9 =? 4 5

Raising a power to a power When raising a power to a power, you multiply the exponents (b 2 ) 3 = b 6 (6 7 ) 4 = 6 28

You try (k 5 ) 6 = (3 4 ) 5

What’s the pattern 3 5 = 243 3 4 = 81 3 3 =27 3 2 = 9 3 1 = 3 3 0 = 1 So what would 3 -1 as fraction =?, 3 -2 3 -3

Exit ticket Negative exponents create what?

What is 345x 0= ?

Negative exponents Negatives exponents make the number flip So if it is a whole number it becomes a fraction If it is in the denominator it moves to the numerator If it is in the numerator than it moves to the denominator

You try

When subtraction leaves you negative

You try
