`(- 2/3)^2xx(- 2/3)^4`

If x=(3/2)^2xx(2/3)^-4 find the value of x^-2

If x = (3/2)^2xx(2/3)^-4 then the value of x^-2 is

Evaluate each of the following: (i)\ (2/(11))^4\ xx\ \ ((11)/3)^2\ xx\ \ (3/2)^3 (ii)\ (1/2)^5\ xx\ ((-2)/3)^4xx\ (3/5)^(-1)

Simplify and express each of the following as power of a rational number: (2/3)^3xx(-6/7)^2xx(-7/4)xx3/2 (iii) -(2/5)^2xx(5/7)^2xx(49)/5+(-4/5)^3xx5/4xx3/4

(((2)/(3))^(3)xx(-(3)/(4))^(2))/([-(2)/(5)]^(3))

Find the sum (1xx2)/(3!)+(2xx(2)^2)/(4!)+(3xx(2)^3)/(5!)+ . . . +(20xx(2)^20)/(22!)

Name the property used in the following. -(2)/(3)xx[(3)/(4)+ (-1)/(2)]=[(-2)/(3)xx (3)/(4)]+[(-2)/(3)xx(-1)/(2)]

3^4 xx (3^5)^(-2) xx ((3^2)/(3^4))^2
