Question

Please answer this question​

Answer 1

2^m+4-2^ m +2=3

2^m(2^4-2^2)=3

2^m(12) =3

2^ m=1/4

2^m=(1/2)^2

Answer 2

${2}^{m + 4} - {2}^{m + 2} = 3 \\ {2}^{m} . {2}^{4} - {2}^{m} . {2}^{2} = 3 \\ {2}^{m} ( {2}^{4} - {2}^{2} ) = 3 \\ {2}^{m} (16 - 4) = 3 \\ {2}^{m} (12) = 3 \\ {2}^{m} = \frac{3}{12} \\ {2}^{m} = \frac{1}{4} \\ {2}^{m} = \frac{1}{ {2}^{2} } \\ {2}^{m} = {2}^{ - 2} \\ m = - 2$
