Answer:

Step-by-step explanation:

(x + 3)^3/2 = 64

√(x + 3)^3 = 64

(x + 3)^3 = 64^2

(x + 3)^3 = (4^3)^2

(x + 3)^3 = (4^2)^3

Same exponent

x + 3 = 4^2

x + 3 = 16

x = 13

TEA [102]

Answer

$\frac{ba-b^{2} }{ab-a^{2} }$

Step-by-step explanation:

$\frac{1-\frac{b}{a} }{1-\frac{a}{b} } = \frac{\frac{a-b}{a}}{\frac{b-a}{b}} = \frac{b(a-b)}{a(b-a)}$

$\frac{ba -b^{2} }{ab-a^{2} }$
