- 84 i

Solution steps

(2 - 49) (- 36)

Apply rule:

a (- b) = - ab

(2 - 49) (- 36) = - 2 - 49 36

= - 2 - 49 36

36 = 6

= - 2 - 49 \cdot 6

Multiply the numbers:

- 2 \cdot 6 = - 12

= - 12 - 49

Apply radical rule:

- a = a - 1

- 49 = 49 - 1

= - 1249 - 1

Apply imaginary number rule:

- 1 = i

= - 1249 i

49 = 7

= - 12 \cdot 7 i

Multiply the numbers:

- 12 \cdot 7 = - 84

= - 84 i

(3 x - 5) (x - 1)^{2}

(- 7 x^{4})^{2}

\frac{3}{4} + \frac{5}{12}

\frac{72}{60}

2 x^{- 1} \cdot 4 x^{2}
