Question

By what number should (18)^-3 be multiplied so that the product is equal to (-3)^-3?
​

Answer 1

$\frac{1}{18 \times 18 \times 18} \times x = \frac{1}{ - 3 \times - 3 \times - 3 }$

$\frac{1}{5832} \times x = \frac{1}{ - 27}$

$x = \frac{5832}{ - 27}$

$x = - 216$

therefore -216 should be multiplied
