数学Ⅲ、指数関数の極限で質問です 写真の問題のくだりが全く分かりません。 なぜ5^xでくくるのか、またなぜその後に答えが∞になるのか分かりません 教えてください🙇

(2) lim (5x-2x) x→∞ = 2 lim5x1 x→∞ - 5 x =8

(2)の、xが存在する範囲と、(3)全ての実数xが成り立つという条件の不等号がよくわかりません。 それとなぜ(3)にはイコールがついているのでしょうか？？ どなたか分かる方教えてください！！🙇‍♀️

基本 8-1 2次不等式の解の条件 (1) 2次方程式 3x2+12x+2m+8=0 が異なる2つの実数解をもつとき,定数mの値 つる 1>0 ある。 さらに、 大 12 ( (2) 2次不等式 2x2-3x+m+1<0 を満たす実数x が存在するようなmの値の範囲 めよ。 2次不等式 4x2-3x+m-1≧0がすべての実数xで成り立つようなmの値の 求めよ。

（2）番です。答えは合っているのですが、私の求めた求め方がたまたまあったのかどうかを知りたいです。教えてください。
