\frac{15}{2}

Solution steps

3 \div \frac{2}{5}

Convert element to fraction:

3 = \frac{3}{1}

= \frac{3}{1} \div \frac{2}{5}

Apply the fraction rule:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{3}{1} \times \frac{5}{2}

Multiply fractions:

3 \times 5 = 15

= \frac{15}{1 \times 2}

Multiply the numbers:

1 \times 2 = 2

= \frac{15}{2}

i^{4} + i^{3} - 3 i^{16} + 4 i^{5}

4 n - 4 m + 3 n - 5 m

512 + 8 m^{6}

ln (ln (e^{e^{8}}))
