Question

(2^3 : 4). 2^n =4

Answer 1

\(\left(2^3:4\right).2^n=4\)

\(\Rightarrow\left(2^3:2^2\right).2^n=2^2\)

\(\Rightarrow2.2^n=2^2\)

\(\Rightarrow2^n=2^1\)

\(\Rightarrow n=1\)

Answer 2

(2^3 :4). 2^n =4

(8 : 4). 2^n = 4

2. 2^n        = 4

2^n            = 4 : 2

2^n            = 2

2^n            = 2^1

=> n = 1

Answer 3

(2^3 : 4) . 2^n = 4

2^3 : 4 = 4 : 2^n

2^n = 4.4:2^3

2^n = 16 : 8

2^n = 2

2^n = 2^1

=> n = 1
