expand (3i10i2i)((3i+10i+2i)/pi)

expand

(3 i \cdot 10 i \cdot 2 i) (\frac{3 i + 10 i + 2 i}{π})

\frac{900}{π}

Decimal Notation

286.47889 \dots

Solution steps

(3 i 10 i 2 i) (\frac{3 i + 10 i + 2 i}{π})

Remove parentheses:

(a) = a

= 3 i 10 i 2 i \frac{3 i + 10 i + 2 i}{π}

Add similar elements:

3 i + 10 i + 2 i = 15 i

= 3 \cdot 10 \cdot 2 iii \frac{15 i}{π}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{15 i 3 i 10 i 2 i}{π}

15 i 3 i 10 i 2 i = 900 i^{4}

= \frac{900 i ^{4}}{π}

900 i^{4} = 900

= \frac{900}{π}

((\frac{2}{x - 12}) + 9 (100 - x)) (x - 4)

3 (33 - 2)

\frac{2 ( x ^{4} + 2 x ^{2} + 4 )}{x ^{2} + 2}

4 (1 - \frac{2}{16} x)^{\frac{1}{2}}

(x - (3 i + 1)) (x - (1 - 3 i))
