Question

27 do potegi 5/3+(1/16)do potegi 1/4= pierwiastek z 2*4 do potegi=

1/3*8pierwistka -1/3= 2do potegi -4 +(4/3)do potegi -2+(2/5)do potegi -3=

[5-3(2/5)do potegi 0]do potegi -2=

Answer 1

27^5/3+1/16^1/4=pierw 3 st z 27^5+pierw 4 stopnia z 1/16=

    =3^5+1/2=243+1/2=243,5

 

pierw z 2 * 4^1/3 * pierw z 8 - 1/3=pierw z2 * pierw 3 st z 4 * 2pierw z 2-1/3=

   =2*2*pierw 3 st z 4-1/3=4-1/3 * pierw 3 st z 4=3,7 pierw 3 st z 4

 

2^(-4)+4/3^(-2)+2/5(-3)= 1/2^4 + 3/4^2 + 5/2^3=1/16 + 9/16 + 125/8 =

                      10/16 +250/16= 260/16=16,25

 

{5- 3 2/5^0}^-2=(5-1)^-2=4^-2=1/4^2=1/16
