1. Simplify on the right side

3n - 5 = -48 - 40n

2. Add '40n' to both sides

3n + 40n - 5 = -48 - 40n + 40n

43n - 5 = -48

3. Add '5' to both sides

43n - 5 + 5 = -48 + 5

43n = -43

4. Divide '43' to both sides

\frac{43n}{43} =  \frac{-43}{43}

n = -1

Which radical expression in the picture is equivalent to t^5/8?
mixas84 [53]
<h3>Answer: Choice B</h3>

=========================================================

Explanation:

The rule we use is

\Large a^{m/n} = \sqrt[n]{a^m} = \left(\sqrt[n]{a}\right)^m

where 'a' is the base, m stays in the role of the exponent, and n plays the role of the root index (eg: n = 3 is a cube root, n = 4 is a fourth root, and so on).

So for instance,

\Large 2^{3/4} = \sqrt[4]{2^3} = \left(\sqrt[4]{2}\right)^3

or in this case,

\Large t^{5/8} = \sqrt[8]{t^5} = \left(\sqrt[8]{t}\right)^5

A flower pot’s base has six sides that are all the same length. Each side measures x−6 units. The base’s perimeter is 78 units.
torisob [31]
6(x-6)=78
6x-36=78
6x-36+36=78+36
6x=114
6x÷6=114÷6
x=19
