Solution steps

- 18 - 10

- 18 = 2 - 9

= 2 - 9 - 10

- 10 = 2 - 5

= 2 - 9 2 - 5

Apply radical rule:

a a = a, a \geq 0

22 = 2

= 2 - 9 - 5

- 9 = 3 i

= 2 \cdot 3 i - 5

- 5 = 5 i

= 2 \cdot 3 i 5 i

Multiply the numbers:

2 \cdot 3 = 6

= 6 i 5 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 6 i^{2} 5

= 65 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 65 (- 1)

Multiply the numbers:

6 (- 1) = - 6

= - 65

2 x^{3} - 3 x^{2} - 9 x + 10

(2 y + 3 x)^{5}

5^{x + 2} + 5^{x + 1}

107 + 428 - 663

(2 a^{3} + 5 b^{4})^{3}
