Question

determinati numarul x=16+4*{2+√2*[√2+3*(√27-3√3)]-7⁰}:(-1)⁷.plss am nevoie pana maine.​

Answer 1

Răspuns:

• x = 4

Explicație pas cu pas:

x = 16 + 4 x {2 + √2 x [√2 + 3 x (√27 - 3√3)] - 7⁰} : (-1)⁷  =

  = 16 + 4 x {2 + √2 x [√2 + 3 x (3√3 - 3√3)] - 1} : (-1) =

  = 16 + 4 x {2 + √2 x [√2 + 3 x 0] - 1} ; (-1) =

  = 16 + 4 x {2 + √2 x [√2 + 0] - 1} : (-1) =

  = 16 + 4 x {2 + √2 x √2 - 1} : (-1) =

  = 16 + 4 x {2 + 2 - 1} : (-1) =

  = 16 + 4 x 3 : (-1) =

  = 16 + 12 : (-1) =

  = 16 - 12 =

  = 4

Answer 2

Răspuns:

x=4

Explicație pas cu pas:

x=16+4*{2+$\sqrt{2}$*[$\sqrt{2}$+3*($\sqrt{27}$-3$\sqrt{3}$)]-$7^{0}$}:$(-1)^{7}$

x=16+4*{2+$\sqrt{2}$*[$\sqrt{2}$+3*(3$\sqrt{3}$-3$\sqrt{3}$)]-$7^{0}$}:$(-1)^{7}$

3*(3$\sqrt{3}$-3$\sqrt{3}$)=3*0$\sqrt{3}$=0

x=16+4*[2+$\sqrt{2}$*($\sqrt{2}$+0)-$7^{0}$]:$(-1)^{7}$

x=16+4*(2+$\sqrt{2}$*$\sqrt{2}$-$7^{0}$):$(-1)^{7}$

x=16+4*(2+2-1):$(-1)^{7}$

x=16+4*3:$(-1)^{7}$

x=16+12:(-1)

x=16-12

x=4
