Question

What is the solution to the equation log 2 x – log 2 4 = 5 ?

Answer 1

log_2 (4) = 2

log_2 x = 7

x = 2^7

Answer 2

128

Answer 3

yep

Answer 4

use log laws

log (x/4) = 5

take the exponential

2^(x/4) = 2^5

Answer 5

then x /4 = 32

Answer 6

so is it 128 or 32 cus i got 128

Answer 7

lol... x/4 = 32 multiply both sides by 4 to find x

x = 128
