Question

1.Oblicz
7²=
(⅗) ⁻²=
(1⅓)⁻¹=
(-8)⁻²=
(-0,3)⁻²=
(-¼)²=
5⁻²=
(√2)²=
2.Zapisz W Postaci Potęgi i oblicz wartośc wyrażenia (zastosuj tw. o potęgach)
4²*4=
6⁵:6³=
(3⁶:3²) * 3 =
(-5)⁶:(-5)⁴ * (-5)²=
2⁻² + 2⁻¹ =

Answer 1

1.Oblicz
7²=49
(⅗) ⁻²=(5/3)²=25/9
(1⅓)⁻¹=(4/3)⁻¹=3/4
(-8)⁻²=(-1/8) ²=1/64
(-0,3)⁻²=(-3/10)⁻²=(-10/3)²=100/9
(-¼)²=-4²=16
5⁻²=(1/5)²=1/25
(√2)²=2
2.Zapisz W Postaci Potęgi i oblicz wartośc wyrażenia (zastosuj tw. o potęgach)
4²*4=4³=64
6⁵:6³=6²=36
(3⁶:3²) * 3 =3 do pot 4 *3= 3 do pot 5
(-5)⁶:(-5)⁴ * (-5)²=(-5) do pot 4
2⁻² + 2⁻¹ =2 do pot -3

Answer 2

1.
7²=7*7=49
(⅗)₋²=-9/25
(1⅓)⁻¹=-1⅓
(-8)⁻²=64
(-0,3)⁻²=0,09
(-¼)²=1/16
5⁻²=-25
(√2)²=2
2.
4²*4=(2²)²*2²=2₄*2²=2⁶
6⁵:6³=(2³)⁵:(2³)⁵=2⁸:2³=2⁵
(3⁶:3²) * 3 =3⁴*3=3⁵
(-5)⁶:(-5)⁴ * (-5)²=-(5)²*(-5)₂=(-5)⁴
2⁻² + 2⁻¹ =-4-2=2₋³

Nie jestem pewna 2 zad.Pozdro; )
