a) 16*(1/2)^4+(-27)*(-2/3)^2= 16*1/16+(-27)*4/9
1-12=-11
b) 2^6*(1/2)^3+(2/3)^4*(1 1/2)^3-64*(1/2)^5=
64*1/8+16/81*27/8-64*1/32=
8+2/3-2=6+2/3=18/3+2/3=20/3=6 2/3
Ps.
Skrót:
^2-do potęgi np.2
a) 16*(1/2)⁴+(-27)*(-2/3)²=
16*1/16+(-27)*4/9=
1-12=-11
b) 2^6*(1/2)³+(2/3)⁴*(1 1/2)³-64*(1/2)^5=
64*1/8+16/81*27/8-64*1/32=
8+2/3-2=6+2/3=18/3+2/3=20/3=6 2/3
