Answer:
5⁴a²
Step-by-step explanation:
(5³a³)÷5a-¹×5-²a²
5³a³÷5a-¹×5-²a²
5³a³÷5¹-²×a-¹+²
5³a³÷5-¹a
5³a³/5-¹a
5³-(-¹)a³-¹
5⁴a²

Answer:
24  Domain: s>=2  or s<=-2
25. 3x^2 +14x +10
26. x^2 -2x+5   
Step-by-step explanation:
24.  Domain is the input or s values
square roots must be greater than or equal to zero
s^2-4 >=0
Add 4 to each side 
s^2 >=4
Take the square root
s>=2  or s<=-2
25.  f(g(x))  stick g(x) into f(u) every place you see a u
f(u) = 3u^2 +2u-6
g(x) = x+2
f(g(x) = 3(x+2)^2 +2(x+2) -6
Foil the squared term
        = 3(x^2 +4x+4) +2x+4-6
Distribute
        = 3x^2 +12x+12 +2x+4-6
Combine like terms
    =3x^2 +14x +10
26 f(g(x))  stick g(x) into f(u) every place you see a u
f(u) = u^2+4
g(x) = x-1
f(g(x) = (x-1)^2 +4
 Foil the squared term
          = (x^2 -2x+1) +4
          = x^2 -2x+5
