intervalnotation |x|>11

解答

interval notation

∣ x ∣ > 11

(- \infty, - 11) \cup (11, \infty)

求解步骤

∣ x ∣ > 11

∣ x ∣ > 11 : x < - 11 or x > 11

Interval Notation for

x < - 11 : (- \infty, - 11)

Interval Notation for

x > 11 : (11, \infty)

合并区间:

(- \infty, - 11) \cup (11, \infty)

数字行

(- \infty, - 11) \cup (11, \infty)

r a d i c a l 125 0^{\frac{3}{4}}

s im pl i f y lo g_{10} (x) + lo g_{10} (x^{2}) - 16 - lo g_{10} (11) - lo g_{10} (x) + 4

24/8

so l v e f or x, lo g_{3} (81) = x

so l v e f or x, lo g_{2} (3 x) - 7 = 3
