Answer:
It’s 2^2
Step-by-step explanation:
Because when it’s squared you get 2*2 and that’s 4
The value of x in log2 (x)-3 = 1 is 2.
What is a logarithm?
"A logarithm is a power to which a number must be raised in order to get some other number. The logarithm is the inverse function of exponentiation".
For the given question,
The expression is given as log2 (x)-3=1
The general form is expressed as
logb (n) = x, then
n = b^x
So, [tex]log_{2}(x) -3 = 1[/tex]
⇒ [tex]log_{2}(x) = 4[/tex]
⇒ [tex]2^{x}=4[/tex]
⇒ [tex]2^{x}= 2^{2}[/tex]
⇒ [tex]x=2[/tex]
Hence we can conclude that the value of x in log2 (x)-3 = 1 is 2.
