Question

ma ajuta cineva va rog​

Answer 1

1. 24=24²=576

35=35²=1225

2. 8=8³=512

13=13³=2,197

3. a) $5^{3} *5^{5} :5^{6}=5^{2} =25$

b) $(2^{3} )^{3} *(2^{4} )^{3} =2^{21}$

c) (nu vad ce scrie la puteri din pacate)

4.

$1^{42} >42^{0} \\\\16^{5} > 64^{3}$

5. (nu stiu modelul din caiet si nici nu se vede la ce putere este 3)

6. a) $(2+2^{2} +2^{3}) :(10^{1} -3)=(2+4+8):7=14:7=2$

b)

$(16*12^{10}-4*12^{10}):12^{11} = 12^{10} *(16-4):12^{11}=12^{10}*12:12^{11}=12x^{11}:12^{11}=1$

7.

$13^{2}+5*((2316:579+[ 40+2^{3}*(2^{4} *5^{2}:10-2^{2}*3^{2} )]*5))+11=\\=169+5*((4+[40+8*(16+25:10-4*9)]*5))+11=\\=169+5*((4+[40+8*(40-36)]*5))+11=\\=169+5*((4+[40+8*4]*5))+11=\\=169+5*((4+[40+32]*5))+11=\\=169+5*((4+72*5))+11=\\=169+5*((4+360))+11=\\=169+5*364+11\\=169+1820+11=2000$
