Answer 1

Răspuns:

Nui bun cum e acolo

Explicație pas cu pas:

Xegal cu 15+radical 90ori 90=

=xegalcu 15+4050= 4035

=x=4035

Answer 2

x=(3 3/5)-¹+√0,8(3)×0,0(3)=

(18/5)-¹+√(83-8)/90×3/90=

5/18+√75/90×3/30=

5/18+√(25×3×3)/(30×3×30)=

5/18+5×3/30×1/√3=

5/18+²√3/6=(5+2√3)/18

y=7/(2√3)×[0,125-0,25+(-1)-⁸]-¹=

7√3/6×[125/1000-25/100+1]-¹=

7√3/6×(1/8-²1/4+⁸1)-¹=7√3/6×(7/8)-¹=

7√3/6×8/7=4√3/3
