Question

rezolvati ecuatia asta pas cu pas va rog, dau coroana

Answer 1

$\displaystyle\bf\\\sqrt{x-1}=6~|^2 \implies |x-1|=36 \implies x-1=\pm 36.\\1.~x-1=36 \implies x=37.\\2.~x-1=-36 \implies x=-35,~dar~pentru~x=-35,~-35-1<0 \implies \sqrt{x-1}~este~nedifinit.\\prin~urmare~:~\boxed{\bf x=37}~.$

Answer 2

Răspuns:

37

Explicație pas cu pas:

Salutare !

V(x - 1) = 6

x - 1 = 36

x = 36 + 1

x = 37

" V " inseamna radical
