Question

44 punkty do zgarnięcia !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Siemka, proszę o rozwiązanie
20^10*(20^8*20^2=
2^8*4 / 2^5= ( to jest w ułamku )
(2^5*8):32=
5^2*25=
(2^5*8):32=
(2^7)^6=
(-0,1)^7*(-0,1)^3=
(a^4*a^3):a^2=
16^5*16^12:16^8
(x^7:x^2):x^5=

Answer 1

20^10*20^8*20^2=20^18*20^2=20^20
2^8*4 / 2^5= 2^8*2^2/2^5=2^10/2^5=2^5
(2^5*8):32=(2^5*2^3):2^5=2^8:2^5=2^3
5^2*25=5^2*5^2=5^4
(2^5*8):32=(2^5*2^3):2^5=2^8:2^5=2^3
(2^7)^6=2^42
(-0,1)^7*(-0,1)^3=0,1^21
(a^4*a^3):a^2= a^7:a^2=a^5
16^5*16^12:16^8=16^17:16^8=16^9
(x^7:x^2):x^5=x^5:x^5=1

Answer 2

=20^10*2^10=20^20
=2^8*2^2/2^5=2^10/2^5=2^5
=2^5*2^3:2^5=2^3 
=5^2*5*2=5^4
=(tu przykład ten sam co w 3)
=2^42
=(-0,1)^10
=a^7;a^2=a^5
=16^17;16^8=16^9
=x^5:x^5=1
