Answer 1

Resposta:

EXERCÍCIOS 1

√7*√7= 2,64 * 2,64 = 6,96

√5*√4= 2,23 * 2 = 4,46

√9*√7= 3 * 2,64 = 7,92

√25*√6=5*2,44 = 12,20

√7*√10= 2,64 * 3,16 = 8,34

√9*√4= 3 * 2 = 6

EXERCÍCIOS 2

√6*(√6-4) = 2,44 * (2,44 - 4) = 2,44 * (-1,56) = -3,80

(√7+√1)*(√7+5) = (2,64+1) * (2,64+5) = 3,64 * 7,64 = 27,80

(√9-4)*(5-√9) = (3-4) * (5-3) = -1 * 2 = -2

√6*(√6+2) = 2,44*(2,44+2) = 2,44*4,44 = 10,83

(9√2+2)*3(√2) = (9*1,41+2) * (3*1,41) = 30,69 * 4,23 = 129,81

√9*(1-√5) = 3 * (1-2,23) = 3*-1,23= -3,69
