Пошаговое объяснение:
1) 0,5 * √0,04 + 1/6 * √144=
=0,5*0,2 + 1/6*12=
=0,1 + 2 = 2,1;
2) 2 * √1 9/16 - 1=
=2 * √25/16 - 1=
=2 * 5/4 - 1=
= 2,5 - 1 = 1,5;
3) (2√0,5)² = 2² * (√0,5)² = 4 * 0,5 = 2;
4) √0,25 * 64 = √0,25 * √64 = 0,5 * 8 = 4;
5) √15*10*6 = √900 = 30;
6) √56 * √14 = √56*14 = √784 = 28;
7) √5/√500 = √5:500 = √0,01 = 0,1;
8) √3 6/25 * 2 2/49 = √81/25 * √100/49 =
= 9/5 * 10/7 = 18/7 = 2 4/7;
9) √2,7 * 120 = √324 = 18;
10) √3⁴*2⁶ = √3⁴ * √2⁶ = 3² * 2³ = 9 * 8 = 72.
