Answer 1

a)0,2²= 0,04b)0,1-¹ =  (1/10)^-1 ==> (10^-1)^-1 ==> 10^1 => 10c)3,4¹=  3,4d)(-4,17) º = 1e)0,05-²=  (5/100)^-2 ==> ( 100/5)^2 ==> 20^2 ==> 400f)l,25¹= 1,15  g)1,2³ = (12/10) = 1728/1000 ==> 1,728h)(-3,2)²= 10,24i)0,6³ = 0,216j)0,08 -¹ =  (8/100) -¹ ==> 100/8k)(-0,3)-¹ = (-3/10) -¹ ==> - 10/3l)(-0,01)-² = (- 1/100)-² ==> (100/1)² ==> 10.000
