simplify 1/2*90

Solution

simplify

\frac{1}{2} \cdot 90

45

Solution steps

\frac{1}{2} \cdot 90

Convert element to fraction:

90 = \frac{90}{1}

= \frac{1}{2} \cdot \frac{90}{1}

Apply the fraction rule:

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

= \frac{1 \cdot 90}{2 \cdot 1}

\frac{1 \cdot 90}{2 \cdot 1} = 45

= 45

2^{\frac{1}{2}} \cdot 2^{3}

(2 i - 1)^{2} (\frac{4}{1 - i} + \frac{2 - i}{1 + i})

\frac{- 1 + 2 i}{- 1 - 2 i}

\frac{2 ( - 0.49 ) + 1}{\frac{1}{4} - ( - 0.49 ) ^{2}}

\frac{2 x}{3} + 5 = \frac{5 x}{3} + 2
