Question

A) √12+√48=

B) √32+√8+√128=

Answer 1

6+8= 14 e assim mesmo no outro

Answer 2

a)
= √12 + √48
= √4.√3 + √16.√3
= 2√3 + 4√3
= 6√3

12: 2
6: 2
3: 3
1      =  4.3 = √4.√3 = 2√3

48: 2
24: 2
12: 2
6: 2
3: 3
1       = 2.2.2.2.3 = 16.3 = √16.√3 = 4√3

b)
√32 + √8 + √128
√16.√2 + √4.√2 + √64.√2
4√2 + 2√2 + 8√2
6√2 + 8√2
= 14√2

32: 2
16: 2
8: 2
4: 2
2: 2
1       = 2.2.2.2.2 = 16.2 = √16.√2 = 4√2

8: 2
4: 2
2: 2
1     =  4.2 = √4.√2 = 2√2

128: 2
64: 2
32: 2
16: 2
8: 2
4: 2
2: 2
1      2.2.2.2.2.2.2 = 64.2 = √64.√2 = 8√2
