Solution

simplify

12 8^{\frac{1}{7}}

Solution

2

Solution steps

12 8^{\frac{1}{7}}

Factor the number:

128 = 2^{7}

= (2^{7})^{\frac{1}{7}}

Apply exponent rule:

(a^{b})^{c} = a^{b c}, a \geq 0

= 2^{7 \cdot \frac{1}{7}}

7 \cdot \frac{1}{7} = 1

= 2^{1}

Apply exponent rule:

a^{1} = a

= 2

Popular Examples

y^{2} + 4 y = 0

simplify ((a^{2/3})/(b^{4/3)})^{3/4}simplify

(\frac{a ^{\frac{2}{3}}}{b ^{\frac{4}{3}}})^{\frac{3}{4}}

x/3+3x-(x-2)/4 = 1/4+x

\frac{x}{3} + 3 x - \frac{x - 2}{4} = \frac{1}{4} + x

simplify (5+i)/(-3-2i)simplify

\frac{5 + i}{- 3 - 2 i}

(x-1)/(-3)+1/5 <= x/2-3

\frac{x - 1}{- 3} + \frac{1}{5} \leq \frac{x}{2} - 3
