Решите неравенство, log 2 (2x+1)> 4

1. the telephone on his table ………………… ( rang ) and he ………………. (picked it up ). 2. pasha …………………………………. (has been reading ) the book for a month but he ..…..………………….. (has read ) only ten pages. 3. it ………………………….

( left ). 7. why are so red? ………… ( have you been lying) in the sun? 8. i don’t want any coffee. i ……………………… ( have drunk ) two cups so far.

Log₂(2x + 1) > 4 log₂(2x + 1) > log₂2⁴ так как основание логарифма больше единицы, функция log₂x - возрастающая, значит 2x + 1 > 16 2x > 15 x > 7,5 ответ: x ∈ (7,5 ; + ∞)
