Question

[(-2)^0 + 2^-2] : (-2)^-2=?

-2 la puterea 0 + 2 la puterea -2 totul impartit la -2 la puterea -2

*vreau sa vad rezolvarea, mersi*

Answer 1

-2 la 0 = 1
2 la -2 = 1/2 la puterea 2 = 1/4
1 + 1/4 = 5/4

-2 la -2 = -1/2 la 2 = 1/4

5/4 : 1/4 = 5/4 inmultit cu 4/1 = 5

Answer 2

[(-2)⁰ + 2⁻²] : (-2)⁻²=(1+1/2²) : 1/2²= 1:1/4+1/4:1/4=  1*4+1=4+1=5
