Question

Utilizand regulile de calcul cu puteri,efectueaza calculele :
A)4^25:4^23-3^23:3^21=
B) (14-11)^25:(23-20)^23=
C) (3^3)^8:(3^6•3^4)=
D) 24^3:6^3-4^23:4^20=
E) 5^176•5^0•5^24:5^199=
F) 2^24•3^24-6^24=
G) (5^7+5^8+5^9):5^6=
H) (7^4+2•7^5+3•7^6):162=
INDICATIE :24^3:6^3=(24:6)^3=4^3
^ inseamna la puterea ...
va rog mult ,mult de tot ...mersi :))

Answer 1

A) 4^25:4^23-3^23:3^21=4²-3²=16-9=7
B) (14-11)^25:(23-20)^23=3^25:3^23=3²=9
C) (3³)^8:(3^6•3^4)=(3³)^8:3^10=27:3=9
D)24³:6³-4²³:4^20=4³-4³=0
E)5^176•5^0•5²⁴:5^199=5^176•5²⁴:5^199=5^200:5^199=5¹=5
F)2²⁴•3²⁴-6²⁴=6²⁴-6²⁴=0
G) (5^7+5^8+5^9):5^6=5²⁴:5^6=5^18

doar atât stiu
sper că te-am ajutat, succes☺️
