d)[(-0,1)²]³

e)(0,2³)²

f)[-(-0,1)²]³

g)(-3a²b)³

h)(-ab²cd²)⁵

i)[(½ab)³*(2b²)²]³

na jutro ! ;)

Answer 1

a) [(-1)²] ³¹ = (-1)⁶²=1

b)(1³) ¹⁵=1⁴⁵=1

c)[-(-1)⁷] ⁴[(-(-1)]²⁸=1

d)[(-0,1)²]³=(-0,1)⁶=0,000001

e)(0,2³)²=(0,2)⁶=0,000064

f)[-(-0,1)²]³=[-(-0,1)]⁶=0,000001

g)(-3a²b)³=-27a⁶b³

h)(-ab²cd²)⁵=-a⁵b¹⁰c⁵d¹⁰=(-ac)⁵(bd)¹⁰

i)[(½ab)³*(2b²)²]³=[(1/8a³b³)(4b⁴)]³=[½a³b⁷]³=1/8a⁹b²¹
