tolong bantu tugas matematika kelas 10plisss

semoga membantu yaa ^^

1.
V50 = V(25 × 2) = 5V2

2.
(-64.a^3.b^2)^1/3
= ((-4)^3.a^3.b^2)1/3
= (-4)ab^(2/3)

3.
(81.a^3.b^5)^1/4
= (3^4a^3b^5)^1/4
= 3a^(3/4)b^(5/4)

4.V(3/2)
= (V3)/(V2)
= (V3/V2) × (V2/V2)
= V6/V4
= (V6)/2
= (1/2)V6

5.
(49a^2)^1/4
= (7^2a^2)^1/4
= 7^(2/4)a^(2/4)
= 7^(1/2)a^(1/2)
= V(7a)
