Drag the tiles to the correct boxes to complete the pairs.
Len [333]

<u>Answer:</u>

1. (-2^2)^{-6} ÷ (2^{-5})^{-4} \implies 2^{-32}

2. 2^4 . (2^2)^{-2} \implies 1

3. (-2^{-4}).(2^2)^0 \implies -2^8

4. (2^2).(2^3)^{-3} \implies 2^{-5}

<u>Step-by-step explanation:</u>

1. (-2^2)^{-6} ÷ (2^{-5})^{-4} :

= \frac{ ( - 2 ^ 2 ) ^ { - 6 } } { ( 2 ^ { - 5 } ) ^ { - 4 } } = \frac{2^{-12}}{2^{20}} = 2^{-12-20}=2^{-32}

2. 2 ^ 4 . ( 2 ^ 2 ) ^ { - 2 } :

= 2^4 \times \frac{1}{2^4} = 1

3. (-2^{-4}).(2^2)^0 :

= (-2^4)^2 \times 1 = -2^8

4. (2^2).(2^3)^{-3} :

= 2^4 \times \frac{1}{2^9} =\frac{1}{2^5} =2^{-5}
