Solution steps

(315) (- 445)

Apply rule:

a (- b) = - ab

(315) (- 445) = - 315 \cdot 445

= - 315 \cdot 445

45 = 35

= - 315 \cdot 4 \cdot 35

15 = 53

= - 353 \cdot 4 \cdot 35

Apply radical rule:

a a = a, a \geq 0

55 = 5

= - 3 \cdot 53 \cdot 4 \cdot 3

Multiply the numbers:

- 3 \cdot 5 \cdot 4 \cdot 3 = - 180

= - 1803

(x + 6)^{2} (x - 9) < 0

\frac{x - 4}{6} \geq \frac{x - 2}{9} + \frac{5}{18}

∣ a ∣ = 0

2 x^{2} - 6 x - 7 = 0

\frac{x ^{4} y ^{8}}{x ^{4} y ^{5}}
