Answer 2

LET THE NUMBER BE = x

Now,

(4/9)^-5 * x = (2/3)^-2

=>(9/4)^5 * x = (2/3)^-2 [the minus is removed by inverting the fraction]

=>(3/2)^5*2 * x = (2/3)^-2

=>(3/2)^10 * x = (2/3)^-2

=> x = (2/3)^-2 * (2/3)^10 [ the fraction becomes inverted as it comes to other side of the equal to sign without any equal stimulant]

=> x = (2/3)^-2+10

=> x = (2/3)^8

=> x= 256/6561

therefore the answer is 256/6561 or (2/3)^8
