WebOct 11, 2024 · Since f ( x) = log x is monotonically increasing ( x > 0) and log 1 = 0, when the base is less than 1, log b is negative and you will need to flip the sign. By the change of base formula, this is equivalent to: n log ( 1 2) ( 1 2) > log ( 1 2) ( 1 4) n > 2 as you have already said.

WebFirst, let us clear out the "/3" by multiplying each part by 3. Because we are multiplying by a positive number, the inequalities don't change: −6 < 6−2x < 12. Now subtract 6 from each part: −12 < −2x < 6. Now divide each part by 2 (a positive number, so again the inequalities don't change): −6 < −x < 3. Webby. Pick Up and Go Resources. $3.00. Zip.
