simplify

\frac{3}{4} (- 2)^{\frac{4}{3}}

\frac{3}{2 ^{\frac{2}{3}}}

Decimal Notation

1.88988 \dots

Solution steps

\frac{3}{4} (- 2)^{\frac{4}{3}}

(- 2)^{\frac{4}{3}} = 2 \cdot 2^{\frac{1}{3}}

= 2 \cdot 2^{\frac{1}{3}} \cdot \frac{3}{4}

Multiply fractions:

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

= \frac{3 \cdot 2 \cdot 2 ^{\frac{1}{3}}}{4}

Multiply the numbers:

3 \cdot 2 = 6

= \frac{6 \cdot 2 ^{\frac{1}{3}}}{4}

Cancel the common factor:

2

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

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = \frac{1}{x ^{b - a}}

\frac{2 ^{\frac{1}{3}}}{2} = \frac{1}{2 ^{1 - \frac{1}{3}}}

= \frac{3}{2 ^{1 - \frac{1}{3}}}

Subtract the numbers:

1 - \frac{1}{3} = \frac{2}{3}

= \frac{3}{2 ^{\frac{2}{3}}}

x^{2} + 3 x - 154 = 0

x + 1 + 3 \leq - 1

18 a^{2} + 12 a + 2

6 m = 6

x^{2} - 4 x + 20 = 0
