Question

(2)^2x-5=1
plzzz answer fast...........​

Answer 1

Answer:

Step-by-step explanation:

2^(2x-5) = 2^0

2x-5=0

X=5/2

Answer 2

Answer:

x = 5/2

Step-by-step explanation:

Given,

(2)^2x-5 = 1

1 can be written as 2^0, Hence

(2)^2x-5 = 2^0

Comparing the powers:

2x-5 = 0

x = 5/2

This can be also done by taking log on both sides:

log(2)^2x-5 = log1

(2x-5)log2 = 0. {log2 ≠0}

2x - 5 = 0

x = 5/2
