#### Storyboard Text

• My friend needs help si﻿mplyfying (A2 ) 4
• Its called power of a power! when you﻿ have an exponent being risen to another exponent, you can mulltiply the exponents
• So  (A2 ) 4    Could be simplifie﻿d to A2x4﻿, and if the base is negative, the same rule applies
• Thank you! Now can you explain the zero law!
• ﻿﻿The ﻿ zero exponent rule basically says that any base with an exponent of zero is equal to one.
• But when its negative it can get a bit confusing...﻿
• When the base is negative (-a)0   It is positive 1 because the negative sign is inside the bracket﻿
• ﻿If the negative symbol is not in the bracket -a0 It is negative 1 because the negative sign is part of the base
• Yay! the last one is power of a product﻿
• When the exponent applies to multiple bases in a bracket, you can add the exponent to each base ﻿
• It sounds confusing, but heres an example (ab)3 can be simplified too a3x b3﻿
• If the bases are negative, you can still simplify it the same way!
• an example is (-a x -﻿b)3  is (-a3   ﻿)  (-b)3
• WERE DONE! LETS GO CELEBRATE﻿
• LETS GO CELEBRATE LEARNING EXPONENT LAWS!
