Step-by-step explanation:

the solutions are as per attached image

Answer 2

Answer:

(i)

$({ \frac{3 }{5} })^{3} \times ( { \frac{3}{5} })^{ - 6} = ( { \frac{3}{5} })^{2x - 1}$

let 3/5 =a

${a}^{3} \times {a}^{ - 6} = {a}^{2x - 1} \\ when \: the \: base \: are \: equal \: power \\ \: are \: added \\ {a}^{3 + ( - 6)} = {a}^{2x - 1}$

now equate the powers

so, 2x-1 = -3

2x= -4

x= -2
