Laws of Exponents Law 1 Law 2 Law 3Law 6 Law 5 Law 4Law 7 Law 8 Law 9

Law 1 x 1 = x Any number raised to the power of 1 equals itself. Show me more! Back to the laws!

Law 1 - examples x 1 = x Back to the laws! 10 1 = 10 6 1 = 6 129 1 = 129 3 1 = 3 z 1 = z b 1 = b y 1 = y t 1 = t

Great job! You did it! On to the next problem! Back to the laws! Thats right! Any number raised to the power of one is itself, so 8 1 = 8.

My turn to practice. Law: x 1 = x Back to the laws! Q2:r 1 = ? s 1t r

Super! Back to the laws! Thats right! Any number raised to the power of one is itself, so r 1 = r. On to the next law!

Oops! Try again! Back to the problem! Remember, any number raised to the power of one is itself!

Law 2 Any number (except 0) raised to the power of 0 equals 1. x 0 = 1 Show me more! Back to the laws!

Law 2 - examples x 0 = 1 Back to the laws! 10 0 = 1 6 0 = 1 129 0 = 1 3 0 = 1 z 0 = 1 b 0 = 1 y 0 = 1 t 0 = 1

Law 3 Any number raised to the power of -1 equals its reciprocal (multiplicative inverse). x -1 = 1/x where x 0 Show me more! Back to the laws!

Law 3 - examples x -1 = 1/x where x 0 Back to the laws! 10 -1 = 1/10 6 -1 = 1/6 129 -1 = 1/129 3 -1 = 1/3 z -1 = 1/z b -1 = 1/b y -1 = 1/y t -1 = 1/t
