Answer 2

a. (2^5)^5:[(-2)^6•2^1]•8^2
= 2^25:[2^6•2^1]•(2^3)^2
=2^25:2^7•2^6
=2^18•2^6
=2^24

b.2^4•(-2)^3:[(-2)^15:2^10]
= (-2)^7:(-2)^5
=(-2)^2
= 4

c. 3^5•27^2:(-9)^5
= 3^5•(3^3)^2:[-(3^2)^5]
= 3^5•3^6:(-3)^10
=3^11:3^10
= 3

d. -5^2^3:(-5)^7•5:25^0
= (-5)^8:(-5)^7•5:1
= (-5)^1•5:1
=-5•5:1
= -25

e. 21^45:(-3)^43:(-7)^43
= (3•7)^45:(-3)^43:(-7)^43
= 3^45•7^45:(-3)^43:(-7)^43
= 3^43•3^2•7^43•7^2:(-3)^43:(-7)^43
= -1:(-1)•3^2•7^2
= 49•9
= 441

f. -5^100:25^49-(-3^4)^5:(3^2)10
= 5^100: (5^2)^49-(-3)^20:3^20
=5^100:5^98-1
=5^2-1
=25-1
=24
