Question

1.aflati patrimea numerelor: 0,1,6,11,12,15,20,21,27.
2.care este patrimea perfecta cuprinsa intre 30 si 40. trebuie justifivat nu direct raspunsul.
3.comparati cubul lui 12 cu patrimea lui 64.
4.la patru uitativa pe imagine .
5.scrieti cubul perfect cuprins intre 25 si 600.
va rog. dau si coroana

Answer 1

0,1,6,11,12,15,20,21,27.
0:4=0
1:4=0,25=25/100
6:4=1,5=15/10
11:4=2,75=275/100
12:4=3
15:4=3,75=375/100
20:4=5
21:4=5,25=525/100
27:4=6,75=675/100
2)
3)12³=1728=3³×$2^{6}$
64:4=16=$2^{4}$
evident 12³>1/4 din 64
5)cubul perfect dintre 25 si 600
 3³=27, 4³=64,  5³= 125; 6³=216, 7³=343, 8³=512
4)
16=4²
121=11²
144=12²
256=16²
324=18²
441=21²
2500=50²
a=3²+4²=9+16=25=5²
b=36+64=100=10²
c=81+144=225=15²
d=144+256=400=20²
c)
$a) 81=9^{2} \\ \\ b)3^{8}=(3^{4})^{2} \\ \\ c) (2^{2})^{2} \\ \\ d)( 5^{2})^{2} \\ \\ e)6 ^{8} = (6^{4})^{2} \\ \\ f)2^{6} =(2^{2})^{3} \\ \\ g)9^{2} ^{10}= (9^{10})^{2}$
