Question

(-3)^2 + (-3)^3 -(-3)^-1 = -17 2/3 show that the following is true​

Answer 1

Answer:

$(-3) {}^{2} +(-3) {}^{3} -(-3) {}^{ - 1} =-17 \frac{2}{3}$

$9 - 27 + \frac{1}{3} = - 17 \frac{2}{3}$

$\frac{27 - 81 + 1}{3} = - 17 \frac{2}{3}$

$\frac{28 - 81}{3} = - 17 \frac{2}{3}$

$\frac{ - 53}{3} = - 17 \frac{2}{3}$

$- 17 \frac{2}{3} = - 17 \frac{2}{3}$
