8^{3x - 1} = 2^8 ; 8 = 2^3 \\
(2^3)^{3x-1} = 2^8 \\
2^{9x-3} = 2^8 \\
9x-3=8 \\
9x=11 \\
x= \frac{11}{9}

8^{(3x-1)}=2^8 \\\\ 2^{3(3x-1)}=2^8 \\\\ 3(3x-1)=8 \\\\ 9x-3=8 \\\\ 9x=8+3 \\\\ 9x=11 \\\\ \boxed{x=\frac{11}{9}}

\sqrt[8]{48^4}  can be rewritten as 48^4 to the \frac{1}{8}  power:

(48^4)^ \frac{1}{8}

Now, applying exponent rules (multiply exponent inside parentheses by the one outside parentheses), we get:

(48^ \frac{1}{2})

This is equivalent to \sqrt{48}, so now, we just simplify:

\sqrt{48}=  \sqrt{16*3}= \sqrt{16}* \sqrt{3}=4 \sqrt{3}

So:

\sqrt[8]{48^4} =4 \sqrt{3}

The volume of a cube is 27 cubic meters. what is its surface area in square meters?
erma4kov [3.2K]

To find the answer, take the measurement of an edge of the cube, multiply it by 6, and then square that number.

Ex:

Edge = 16

Faces in 1 cube = 6

     6 * 16 = 96

96^2 (which is just 96 * 96)= 9,216


I hope this helps! :)

y^2 + 16y + 64 = 0

(y + 8)(y+8) = 0

y + 8 = 0

y = -8

y + 8 = 0

y = -8

Which of the following statements describes the process for solving 4x ≥ -24?
dezoksy [38]
Divide both sides of the inequality by 4 but don’t flip the symbol.

You only flip the inequality symbol if you divide by a negative number.

If you’re solving for x (which you are), you want to get x by itself. The only way to do that is to divide by 4.
