- a) -32
- b) 16
- [tex]c) \: { \red{ \frac{1}{5} }}[/tex]
- [tex]d) \: { \red{ \frac{1}{25} }}[/tex]
Explicație pas cu pas:
a) (-2)⁵=(-2)×(-2)×(-2)×(-2)×(-2)= -32
b) (-2)⁴=(-2)×(-2)×(-2)×(-2)=16
[tex]c) \: {5}^{ - 1} = ( \frac{1}{5} ) {}^{1} = { \red{ \frac{1}{5}}} \\ \\ d) \: ( - 5) {}^{ - 2} = ( \frac{1}{5} ) {}^{2} = { \red{ \ \frac{1}{25}}} [/tex]
Succes!
