Anything to the power of zero is one
4 0 =1 X 0 =1 =?
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
(3 4 )(3 10 ) (y 5 )(y 7 )
If you are dividing and the base number is the same them you subtract T 7 =T 2 T5T5 5 10 =5 1 5959
W 6 =? W 4 4 9 =? 4 5
When raising a power to a power, you multiply the exponents (b 2 ) 3 = b 6 (6 7 ) 4 = 6 28
(k 5 ) 6 = (3 4 ) 5
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 =?,
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
Why is everything to a zero power equal to 1?
