Question

BOA TARDE!
ALGUÉM ME AJUDE POR FAVOR?

simplifique as expressões algébricas. as variáveis representam números positivos:

(a)= √x⁵

(b)= √12a²

(c)= √48b⁴

(d)= 4√81a³b³
ab

(e)= 1√32a³
2a

Answer 1

a) √x^5=√x^4.√x => x².√x => x²√x #
b)√12a²=√4.√3.√a² => 2.√3.a => 2a√3
c)√48b^4=√16.√3.√b^4 => 4√3.b² => 4b²√3 #
d)4/ab.√81a³b³
4/ab.√81.√a³.√b³
36/ab.√(a.b)³
36.√(a.b)³/ab
36.(ab³)^1/2 /ab
36.(ab)^3/2 / ab
36.(ab)^(3/2-1)
36.(ab)^(1/2)
36.√ab = 36√ab #
e) 1/2a;√32a³ => 1/2a.√2^5.√a³ => 1/2a.√16.√2.√a³ => 1/2a.4√2.√a³ =>
(1.4√2.√a³)/2a
(4√2a³)/2a
4.(√2a³)/2.(a)
2.√2a³/a
2.√2.√a².√a/a
2.√2.a.√a/a
2a√2a/a
2.(a)√2a/1.a
2√2a #
