Question

(05.02 MC) Solve 2 log x = log 64. Ox= 1.8 Ox=8 Ox= 32 Ox = 128

Answer 1

Answer:

x = 8

Step-by-step explanation:

$2logx=log64\\logx^2=log64$

now that both sides has log, you can remove them and leave it as:

$x^{2} =64$

take the square root of both sides:

$x = [8, -8]\\x = 8$

logarithmic equations can't have negative solutions, plus -8 isn't an option

i hope this helped!
