write the fraction as a expression using a negetive exponent other than -1

I will give you examples on how to right fractions using negative exponents"


For example we have the fraction:


16/9


This could be written as:


4*4 / 3*3 = 4^2/3^2= (4/3)^2


If you flip the function , you will get a negative exponent:


(4/3)^2 = (3/4)^-2



Another example is sqrt(3)/sqrt(5)


We know that sqrt(3)/sqrt(5) = sqrt(3/5)


We could write the square root as an exponent of (1/2)


Then , sqrt(3/5)= (3/5)^1/2


Now flip and change sign:


(3/5)^1/2 = (5/3)^-1/2
