proszę rozwiązac krok po kroku i proszę odpowiedziec na zadania w formie złącznika
IV skan:
a) 4,2 (x+5) + 1,8 <= -2,4
4,2x + 21 + 1,8 <= -2,4
4,2x <= -25,2
x<= -6
x∈
b) (x+4)²-(x+1)² >= 4(x-1)
x²+8x+16-x²-2x-1≥ 4x-4
2x ≥ -19
x ≥ -9,5
I skan:
-7x=-7
x=1
(x+5)²- (x+3)² = x+1
x²+10x+25-x²-6x-9= x+1
3x=-15
x= -5
III skan :
a¹² * a¹⁰ / a¹⁸ : a²= a²²/a¹⁶=a⁴
(a³)² : a⁴ / a = a⁶ :a⁴ / a = a² / a = a
skan V:
(3⁵ * 3)² *81 = (3⁶)² * 3⁴ = 3¹² * 3⁴ = 3¹⁶
(33³ : 11³ )² : 27² = ( 3³ * 11³ : 11³)² : (3³)² = (3³)² : (3³)² = 1
skan VI:
4 √ 16 = 4 * 4 = 16
2 ⁴√625 = 2 * 5 = 10
3 ³√27 = 3 * 3 = 9
16 - 10 + 9 = 15
5√(-6)² = 5 * 6 = 30
3 ³√-125 = 3 * 0 = 0
2 ⁴√81 = 2 * 3 = 6
3(30 + 0+ 6) = 3 * 36 = 108
i to byłoby na tyle ...
