Answer:

Step-by-step explanation:

Bro only first part only rest you can do yourself

Answer 2

${ (\frac{5}{3} })^{ - 4} \times { (\frac{5}{3} })^{ - 5} = { (\frac{5}{3} })^{3x} \\ \\ { (\frac{5}{3} })^{ - 4 - 5} = { (\frac{5}{ 3} })^{3x} \\ \\ by \: comparing \: both \: sides \\ \\ - 4 - 5 = 3x \\ \\ 3x = - 9 \\ x= -9/3 \\ x = - 3$

( b)

${ (\frac{4}{9} })^{4} \times { (\frac{4}{9} })^{ - 7} = { (\frac{4}{9} })^{2x - 1} \\ \\ power \: be \: added \: when \: base \: is \: same \\ \\ { (\frac{4}{9} })^{4 + ( - 7)} = { (\frac{4}{9} })^{2x - 1} \\ \\ by \: comparing \: both \: sides \\ \\ 4 - 7 = 2x - 1 \\ \\ 2x - 1 = - 3 \\ \\ 2x = - 2 \\ \\ x = - 1$
