Answer 1

Explicación paso a paso:

b)

(3/5)² ÷ (3/5)⁻³

(3/5)²⁻⁽⁻³⁾

(3/5)²⁺³

(3/5)⁵

c)

[(2/5)⁻³]⁻²

(2/5)⁻³ˣ⁻²

(2/5)⁶

Resolver:

2/3x  - 5/x = 7/4 - 3/2x +1

(2*4-5*12)/12x = (7*3x- 3*6 + 1*12x)12x

(8-60)/12x = (21x- 18 + 12x)12x

8-60 = 21x- 18 + 12x

-52 = 21x + 12x -18

-52 = 33x -18

-52 +18 = 33x

-34 = 33x

-34/33 = x
