Question

2^x+2^(x+1)+2^(x+2)+2^(x+3)=15√32​

Answer 1

Answer:

i dont no.......... sorry

Answer 2

Answer:

Step-by-step explanation:

2^x+2^(x+1)+2^(x+2)+2^(x+3)=15sqrt(32)=15sqrt(16*2)=15*4sqrt(2)=60sqrt(2)

2^x+2^x*2^1+2^x*2^2+2^x*2^3=60sqrt(2)

2^x(1+2+4+8)=60sqrt(2)

2^x(15)=60sqrt(2)

2^x=2^2*(2^(1/2))

2^x=2^(2+1/2)

2^x=2^(5/2)

x=5/2
