Answer 1

Respuesta:

Explicación paso a paso:

1)= (4/9+ 1/3) (1/2)⁻²+ 1/2

= (4+3 /9)(2²)+1/2

=(7/9)(4)+1/2

=28/9 +1/2

=56 +9 /18

=65/18   o 3.6111111......

2) ∛(5/3)³+[(1/3)(-3/2)⁻¹]⁻¹

=5/3 + [(1/3)(-2/3)]⁻¹

=5/3+[(-2/9)]⁻¹

=5/3-9/2

=10-27 /6

=-17/6   o -2.83333.....

3)=(25/8).(11/9+5/9)⁻¹+(-1/5)(-25)

=(25/8)(16/9)⁻¹+5

=(25/8)(9/16)+5

=225/128  + 5

=225+640 /128

=865/128  o 6.7578125

4)=√(-20+69/25) + 5/9 -(2/9)⁻²

=√(49/25) +5/9-81/4

=7/5+5/9-81/4

=252+100-3645 /180

=-3293/180  o   -18.294444.....

5) =[(1/2+1/3)(-1/2)]⁻¹+10/9(3)

= [(3+2/6)(-1/2)]⁻¹+10/3

=[(5/6)(1/2)]⁻¹+10/3

=[5/12]⁻¹+10/3

=12/5+10/3

=36+50/15

=86/15  o 5.73333....
