Bunaaa...ma ajutati si pe mine la ex. 2. Va dau coroana promiiiit... ❤❤❤❤

Answer 1

A=25^27×25^26-(1+0+1)^4

A=25-16=9

B=2^7-11×{91-5×[22-5 (40^2-(40^2-1))]}+1^2017

B=2^7-11×{91-5×[22-5 (40^2-40^2+1)]}+1

B=2^7-11×[91-5×(22-5×1)]+1

B=2^7-11×(91-5×17)+1

B=2^7-11×(91-85)+1

B=2^7-11×6 +1=128-66+1=63
