Answer 1

p3st(16) + p3st(2) + p3st(54) =  p3st(8*2) + p3st(2) + p3st(27*2) =

= 2* p3st(2) + p3st(2) + 3*p3st(2) = 6 p3st(2)

=========================================

5^3 * 15^3 * 25^3 *(1/125)^3 =5^3 * (3*5)^3 * (5*5)^3 *[ 1/( 5^3*5^3*5^3)] =

= 5^3 * 3^3*5^3 *5^3*5^3 *( 1/( 5^3 * 5^3 *5^3) = po skróceniu

= 3^3 *5^3 = (3*5)^3 = 15^3 = 3375

Answer 2

∛16+∛2+∛54=∛2×8+∛2+∛2×3×3×3=2∛2+∛2+3∛2=6∛2

5³×15³×25³×(1/125)³=5³×5³×3³×(5²)³×125⁻³=5⁶×3³×5⁶×(5³)⁻³=5¹²×3³×5⁻⁹=5³×3³=(5×3)³=15³=3375
