B)2³×2²×2
C)(7²)⁴
D)(5²)⁴×5⁸:5¹⁵​

Answer 1

Răspuns:

$a)4 {}^{34} \div 4 {}^{32} = 4 {}^{2} \\ b)2 {}^{3} \times 2 {}^{2} \times 2 = 2 {}^{6} \\ c)(7 {}^{2} ) {}^{4} = 7 {}^{8} \\ d)(5 {}^{2} ) {}^{4} \times 5 {}^{8} \div 5 {}^{15} = \\ 5 {}^{8} \times 5 {}^{8} \div 5 {}^{15} = \\ 5 {}^{16} \div 5 {}^{15 } = 5 {}^{1}$

Answer 2

$\it a)\ \ 4^{34}:4^{32}=4^{34-32}=4^2=16\\ \\ b)\ \ 2^3\cdot2^2\cdot2=2^{3+2+1}=2^6=64\\ \\ c)\ \ (7^2)^4=7^{2\cdot4}=7^8\\ \\ d)\ \ (5^2)^4\cdot5^8:5^{15}=5^{8+8-15}=5^1=5$
