Question

g) (0,25)la puterea 7 x (0,25)la puterea 14 : (1/4) la puterea 19 + 0,125=?
h)0,5 x [1/3+1/4 - 0,1(6)] : 2,5=?

Answer 1

g) (0,25)⁷ x (0,25)¹⁴ : (1/4)¹⁹ + 0,125=
=(25/100)⁷ x (25/100)¹⁴ : (1/4)¹⁹ + 125/1000=
=(1/4)⁷ x (1/4)¹⁴ : (1/4)¹⁹ + 1/8=
=(1/4)²¹ : (1/4)¹⁹ + 1/8=
=(1/4)²  + 1/8=
=1/16  + 1/8=
=(1+2)/16 =3/16

h)0,5 x [1/3+1/4 - 0,1(6)] : 2,5=                         0,1(6)=(16-1)/90=15/90=1/6
=5/10 x(1/3+1/4 - 1/6) : 25/10=
=1/2 x (4+3-2)/12 x 2/5=
=1/2 x 5/12 x 2/5=
=1/12
