45 a si b!!!!va roggggg

Answer 1

a) (3^30-2^30+2^30) : (-27)^10
-2^30 cu + 2^30 se anuleaza, iar (-27)^10 se descompune
3^30 : ((-3)^3)10
3^30 : (-3)^10
= -1


b)[3^12-5^8 + ((-5)^2)^4 ] x (-2)^12 -(6^2)^6
(3^12 - 5^8 + (-5)^8 ) x (-2)^12 -6^12

- 5^8 + (-5)^8 se anuleaza
3^12 x ((-2)^12-6^12)
=6^12-18^12
