Answer 2

Step-by-step explanation:

The product of (3/4)^-4 and (-2/3)^2

= (3/4)^-4×(-2/3)^2

when we do reciprocal the power will changes to positive in this case

So,= (4/3)^4×(-2/3)^2

= 4^4/3^4×-2^2/3^2

= 256/12×-4/9

= -256/27

let the number be x

-256/27÷x = (5/3)^2

= -256/27÷x = 25/9

= x = 25/9×27/-256

x = 125/-256

Therefore, x = -0.488
