Question

evaluate (2/3)-3 x (2/3)-2​

Answer 1

Answer:

(2/3) - 3 * (2/3)-2

=( 2-9)/3 * (2-6) /2

= -7/3 * -4/2 = 28 / 6 = 4.667

Answer 2

Answer:

Step-by-step explanation:

Given,

(2/3)^-3 × (2/3)^-2

= Bases are equal then powers should be add

= (2/3)^- 3 - 2

= (2/3)^- 5

= 1 / (2/3)^5 (since, a power - m = 1 / a power m)

= 1 / [ (2)^5 / (3)^5]

= 1 / [ 32 / 243]

= 243 / 32

= 7.59 is the answer.
