Explicație pas cu pas:

$\large \bf a)~~(0,4)^{2} =0,4 \cdot 0,4 = \boxed{\bf 0,16}$

$\large \bf b)~~(2,5)^{2} =2,5 \cdot 2,5 = \boxed{\bf 6,25}$

$\large \bf c)~~(1,6)^{2} =1,6 \cdot 1,6 = \boxed{\bf 2,56}$

$\large \bf d)~~(4,1)^{2} =4,1 \cdot 4,1 = \boxed{\bf 16,81}$

$\large \bf e)~~(0,02)^{3} =0,02 \cdot 0,02 \cdot 0,02 = \boxed{\bf 0,000008}$

$\large \bf f)~~(2,9)^{3} =2,9 \cdot 2,9 \cdot 2,9 = \boxed{\bf 24,389}$

$\large \bf g)~~~(0,05)^{3} =0,05 \cdot 0,05 \cdot 0,05 = \boxed{\bf 0,000125}$

$\large \bf h)~~(0,001)^{6} =\bigg(\dfrac{1}{1000}\bigg)^{6} = \boxed{\bf \dfrac{1}{1000^{6}}}$

Answer 2

$\it 0,4^2=0,4\cdot0,4=0,16\\ \\ 2,5^2=2,5\cdot2,5=6,25\\ \\ 1,6^2=1,6\cdot 1,6=2,56\\ \\ 4,1^2=4,1\cdot4,1=16,81\\ \\ 0,02^3=0,02\cdot0,02\cdot0,02=0,000008\\ \\ 2,9^3=2,9\cdot2,9\cdot2,9=24,389\\ \\ 0,5^3=0,5\cdot0,5\cdot0,5=0,125$
