Answer 1

Answer:

√a/b= (b/a)^1-3x

(a/b)^1/2= (a/b)^-{1-3x}

equting exponents we get,

1/2= 3x-1

3x= 1/2+1

3x= 3/2

x= 3/2×1/3

x= 1/2

Answer 2

Square on both sides

$\frac{a}{b} = { \frac{b}{a} }^{2(1 - 3x)}$

$\frac{a}{b} = { \frac{b}{a} }^{2 - 6x}$

$take \: reciprocal \: on \: rhs$

$\frac{a}{b} = { \frac{a}{b} }^{6x - 2}$

$the \: base \: are \: equal \\ so \: exponents \: must \: be \: equal$

$6x - 2 = 1 \\ 6x = 3 \\ x = \frac{1}{2}$
