Answer 1

Răspuns:

Explicație pas cu pas:

√108 = √36*3 = 6√3

√48 = √16*3 = 4√3

√243 = √81*3 = 9√3

√288 = √144*2 = 12√2

√200 = √100*2 = 10√2

____________

6√3 *(4√3 - 9√3) + 6√2*(12√2 - 10√2)

= 6√3*(-5√3) + 6√2*2√2 = -90 + 24 = -66

Answer 2

√108×(√48-√243)+6√2×(√288-√200)=

=6√3×(4√3-9√3)+6√2×(12√2-10√2)=

=6√3×(-5√3)+6√2×2√2=

= -30×3+12×2=

= -90+24= -66
