Answer 1

V98×(3V242-5V32+3V50-2V128)=

3√98×242-5V32×98+3V50×98-2V128×98=

3√23716-5√3136+3√4900-2√12544=

3×154-5×56+3×70-2×112=

462-280+210-224=

672-504=168

Answer 2

Răspuns

Raspuns  =  168

Explicație pas cu pas:

√98*(3√242-5√32+3√50-2√128)=

7√2*(3*11√2-4*5√2+5*3√2-8*2√2)=

7√2*(33√2-20√2+15√2-16√2)=

7√2*(48√2-36√2)=

7√2*12√2=84*(√2)²

84*2=168
