Answer:

130=8x+15 and 14 pairs

Step-by-step explanation:

Y=mx+b Since he has 130 dollars to spend, that is Y. He needs $15 to spend for an uber which would be b in an equation. He spends $8/per jean. 130(total)-15(uber)=$115 left. 115(total now)-8x. 8x14=112. 115(left)=112(14 pairs of jeans)

We can rewrite the expression under the radical as

$\dfrac{81}{16}a^8b^{12}c^{16}=\left(\dfrac32a^2b^3c^4\right)^4$

then taking the fourth root, we get

$\sqrt[4]{\left(\dfrac32a^2b^3c^4\right)^4}=\left|\dfrac32a^2b^3c^4\right|$

Why the absolute value? It's for the same reason that

$\sqrt{x^2}=|x|$

since both $(-x)^2$ and $x^2$ return the same number $x^2$ , and $|x|$ captures both possibilities. From here, we have

The absolute values disappear on all but the $b$ term because all of $\dfrac32$ , $a^2$ and $c^4$ are positive, while $b^3$ could potentially be negative. So we end up with
