Answer 1

1. a) 8 • 32 : 64 = 256 : 64 = 4

b) 8 la puterea 4: 2 la puterea 10=4096: 1024
= 4

c) 512 la puterea 3 : 8 la puterea 8 =
= 134 217 728 : 16 777 216 = 8

d) 64: 64=1

e) 59 049:486= 121. 5

f) (4+2 la puterea 4) : 5 = (4+16): 5=20: 5=4

g) (1+2+4+16): (128+1) =(23: 129)=0.178

h) (27 la puterea 12: 9 la puterea 5-56): 5=
= (3 la puterea 7 - 56) : 5 = (2187-65) : 5 =
= 2122 : 5= 424.4

i) 8 la puterea 16: ( 2 • 16 • 10) la puterea 3-2-1=
= 8 la puterea 16: 320 la puterea 3 -2-1=
= 281 474 976 710 656: 32 768 000-2-1=
= 8 592 032 256125 - 2 - 1 =
= 8 592 032 256123 - 1 = 8 592 032 256123
