Answer 1

Answer:

The value of K is 3

Step-by-step explanation:

$\textsf{Given:}$

$\mathsf{2^{1998}-2^{1997}-2^{1996}+2^{1995}=K\;2^{1995}}$

$\textsf{Taking out 2^{1995} as common}$

$\mathsf{=2^{1995}(2^3-2^2-2^1)=K(2^{1995})}$

$\textsf{cancelling 2^{1995} on both sides}$

$\mathsf{8-4-2+1=K}$

$\implies\boxed{\mathsf{K=3}}$
