Question

repede va rog!!
Doar b,c si d.

Answer 1

b. 2x4x16 : [ 2+4+ 16 : ( 16 - 4x2 ) ] = 128 : [ 6+16 : ( 16-8) ] = 128 : [ 6+ 16:8] = 128 : ( 6+2 ) = 128 : 8 = 16

c. 5^7 : 5^5 + 5^6 : 5^5 + 5^5 : 5^5 + 3^2^7 : 3^ 10

= 5^(7-5) + 5^(6-5) + 5^ (5-5) + 3^( 2x7) : 3^ 10 =

5^2+5^1+5^0 + 3^14: 3^10

5^2+5+1+3^(14-10)

25+5+1+3^4

31+ 81 = 122

d. 3^2+ 24^2 + 2^5 x 5^2 - 1 =

9 + 576 + 32x25 -1 = 585 + 800 - 1 = 1384
