Question

plz help by sending answer on paper sheet. ​

Answer 1

Step-by-step explanation:

so the above equation could be written as

(2^x)^2-8(2^x)=-16

taking 2^x as common

2^x[2^x-8]=-2^2×2^2

Comparing

2^x=2^2 and 2^x-8=-2^2

X=2 and 2^x=-4+8

X=2 and 2^x=4

X=2 and X= 2

so from both u get X=2
