Answer 2

em ơi cho xin cái đề bài

Answer 3

\(\left(2^2:4\right).2^n=1.2^n.thay.n.bằng.4.ta.có:2^4=16\)

Answer 4

\(\left(2^2:4\right).2^n=4\)

\(\Leftrightarrow\left(4:4\right).2^n=2^2\)

\(\Leftrightarrow2^n=2^2\)

\(\Leftrightarrow n=2\)

Answer 5

(2ⁿ:4).2ⁿ = 4

(2ⁿ:2²).2ⁿ=2²

2^n-2.2ⁿ= 2²

2^n-2+n=2²

n-2+n=2

n-2=2-n

n=4-n

n=2

Answer 6

n=2
