2³ = 2*2*2 = 4*2 = 8

2-² = 1/4 = 0.25

3⁴ = 3*3*3*3 = 9*9 = 81

4-¹ = 1/4 = 0.25

Réponse:

[tex]2 {}^{3} = 2 \times 2 \times 2 = 8 \\ 2 {}^{ - 2 } = \frac{1}{2 {}^{2} } = \frac{1}{4} = 0.25 \\ 3 {}^{4} = 3 \times 3 \times 3 \times 3 = 81 \\ 4 {}^{ - 1} = \frac{1}{4 {}^{1} } = \frac{1}{4} = 0.25[/tex]
