Rewrite the constant 3 as a logarithm with base 2:

log0.5(x+1)≥log0.5(0.5-2)log base 0.5 of open paren x plus 1 close paren is greater than or equal to log base 0.5 of open paren 0.5 to the negative 2 power close paren Rewrite the constant 3 as a logarithm with base 2: log0

log0.5(x+1)≥log0.5(4)log base 0.5 of open paren x plus 1 close paren is greater than or equal to log base 0.5 of 4 is between 0 and 1 ( Rewrite the constant 3 as a logarithm with base 2: log0

Both arguments must be positive:

log2(2x−4)>log2(23)log base 2 of open paren 2 x minus 4 close paren is greater than log base 2 of open paren 2 cubed close paren Rewrite the constant 3 as a logarithm with base 2: log0
