Answer 1

16
a
⁵V(-10)⁵ = -10 ***
b
⁴V(121)⁴ = 121 ***
c
³V(8a²)³  = ³V(2³ * a²)³ = 2³ * a² = 8a² ***
17
Equivalente a   ³Va² 
a
₃V(28)⁶ =[ ³V2² * ³V7¹ ]⁶ = ³V2¹² * ³V7⁶ = 16 * 49 = 784
b
⁴V(10)⁻⁴ = ⁴V(1/10)⁴ = 1/10  ****
c
⁵V(1/2)¹⁵ = ⁵V(1/2)⁵  * ⁵V(1/2)⁵ * ⁵V(1/2)⁵ = 1/2 * 1/2 * 1/2 =1/8 ***
d
V(0,2)⁶ = V(0,2)² * V(0,2)² * V(0,2)²  =  0,2 * 0,2 * 0,2 = 0,008

19
a
¹²V(15)¹⁸ = ¹²V(15)¹² * ¹²V(15)⁶ =  15 *  V15¹
b
¹⁰V(xy³)⁸ = ¹⁰V(x⁸y²⁴) = ⁵Vx⁴y¹²
