simplify

- 9 + - 4 - 16

- 4 + 5 i

Solution steps

- 9 + - 4 - 16

- 9 = 3 i

- 4 = 2 i

16 = 4

= 3 i + 2 i - 4

Add similar elements:

3 i + 2 i = 5 i

= 5 i - 4

Rewrite in standard complex form:

- 4 + 5 i

= - 4 + 5 i

- \frac{\frac{16}{5}}{( - \frac{12}{25} )}

lo g_{0.3} (3)

a^{1} x^{3} y^{2} + a^{2} x^{3} y^{2}

\frac{tan ( x )}{sin ( x )}

10 \times \frac{2}{5}
