Simplify the expression. (81x^12/3x^3)^1/3
ser-zykov [4K]
Raise each number to the power outside the parentheses.

\left( \dfrac{81x^{12}}{3x^3} \right) ^{ \frac{1}{3} } = \\

= \left( 27x^{12-3} \right) ^{ \frac{1}{3} } = \\

= \left( 27x^{9} \right) ^{ \frac{1}{3} } = \\

= \left( 3^3x^{9} \right) ^{ \frac{1}{3} } = \\

= \left( 3^3 \right) ^{ \frac{1}{3} } \times \left( x^{9} \right) ^{ \frac{1}{3} } \\

= \left( 3^{3 \times \frac{1}{3} } \right)  \times \left( x^{9 \times  \frac{1}{3} }} \right)  \\

= 3^1 x^3 \\

= 3x^3

What is the solution to 3x + 1 &lt; 2x - 2 &lt; 5x +7
Law Incorporation [45]
This inequality has NO SOLUTION:

PROOF:

3x + 1 < 2x - 2 < 5x +7

1st let's analyze the 1st inequality: 3x+1<2x-2
3x-2x <-2-1 Then x <-3

2nd let's analyze the 2nd inequality: 2x-2 < 5x+7
2x-5x < 7+2 Then  -3x<9 OR 3x > - 9 and x> - 3

In the 1st we have x <-3 in the 2nd we have x > - 3 which is impossible
