Question

a) 3+2•[(2la puterea27 • 3la puterea35)² : (2la puterea51 • 3la puterea69)-4la puterea17:2³³+35]

Answer 1

 $3+2*[ 2^{27*2} * 3^{35*2} ):( 2^{51} * 3^{69} )- 4^{17} : 2^{33} +35 ] = 3+2*( 2^{54} : 2^{51} *$  
$3^{70} : 3^{69} - 2^{2*17} : 2^{33} +35)= 3+2*( 2^{54-51} * 3^{70-69} - 2^{34-33} +35)=$$3+2*( 2^{3} *3 -2+35)= 3+2*(8*3-2+35)=3+2*57=3$$+114=117$
