Answer 1

Scoti termenii de sub radical si obtii:
a. A= 2√5 ( 4√2- 3√2+5√2-2√2)
A= 2√5*4√2=8√10
B= 10 (3√5-5√5+32√5-√5)
B= 10*29√5=290√5
b. A= 4√7 (7√5-3√5+4√5-5√5)
A= 4√7*3√5=12√35
B=12√5 (4√7+3√7-2√7+5√7)
B=12√5*10√7=120√35
c. A= 3√15 (2√5-3√5+7√5-4√5)
A= 3√15*2√5 = 6√75=30√2
B= 5√6 (4√3+7√3-11√3+2√3)
B= 5√6*2√3=10√18=30√2
d. A=9√10 ( 4√2+6√2-9√2+√2)
A= 9√10* 2√2 = 18√20 = 36√5
B= 28√2 ( 3√5 +4√5-5√5+2√5)
B= 28√2 * 4√5 = 112√10
