Question

Evalute: (27)^1÷3×(27)^-1÷3×[27^1÷3-27^2÷3]

Answer 1

Answer:

(-54)

Step-by-step explanation:

(27)^(⅓)×(27)^(-⅓)×[27^(⅓)-27^(⅔)]

= 3×(1/27)^(⅓)×[3-9]

= 3÷(1/3)×[-6]

= 9×[-6]

= -54

(27)^-1/3 (27)^-1/3[27^ 1/3 – 27 ^2/3]

=> ${27}^{-1/3} × {27}^{-1/3} × [ {27}^{1/3} – {27}^{2/3} ]$

=> ${1/27}^{1/3} × {1/27}^{1/3} × [ 3 – 3²]$

=> $1/3 × 1/3 × [ 3 – 9]$

=> $1/9 × – 6$

=> $\large\frac{-2}{3}$
