= 2⁵+(2)⁵=
= 2*2⁵=
= 2⁶
(⅓)⁴+(⁻⅓)⁴=
=(1/3)⁴ + (1/3)⁴ ( bo (-1/3)⁴ = (1/3)⁴
= 2*(1/3)⁴
(⅓)²•3²=
=(3)-² * 3²=
= 3 ⁰=
= 1
10³•0,1²=
= 10³ * (1/10)²=
= 10³ * (10)-² =
= 10
⅓•3²+¼•2²=
= (1/3)*9 + (1/4)*4 =
= 3 + 1 =
= 4 =
= 2²
2•0,2³-0,2³=
= 2*(1/5)³ - (1/5)³ =
=(1/5)³*( 2 -1) =
=(1/5)*1 =
= 1/5 =
= 5^(-1)
