Question

Problema 3 subiect 2 . Urgent! La primu dau coroana!

Answer 1

Răspuns:

Explicație pas cu pas:

a = [(2^15 : 2^12 + 2^10 : 2^5(3 + 1)] *2^65

= (2^3 + 2^10 : 2^7)*2^65 = (2^3 + 2^3)*2^65 = 2*2^3*2^65 = 2^69 = (2^23)^3

a = cub perfect

Answer 2

[(2⁵)³:(2³)⁴+2¹⁰:(3x2⁵+2⁵)]x(2¹³)⁵=

[2¹⁵:2¹²+2¹⁰:(2²x2⁵)]x2⁶⁵=

(2³+2¹⁰:2⁷)x2⁶⁵=

(2³+2³)x2⁶⁵=

2x2³x2⁶⁵=

=2⁶⁹

=2²³x2²³x2²³

=(2²³)³

Succes!
