Given:
(4k⁷)³ = 4n(k⁷)³

Note that (aˣ)ⁿ = aˣⁿ

Expand the left and right sides.
4³k²¹ = 4nk²¹
Divide each side by k²¹.
4³ = 4n
Divide each side by 4.
4² = n
Therefore
n = 4² = 16

Answer: n = 16

1- Caleb's family room has the dimensions shown. He needs to find the area of the room so that he knows how much carpet to buy.

Rina8888 [55]

Answer: $20\frac{11}{32}\ sq\ yd$

Step-by-step explanation:

Given: The width of the room = $3\frac{7}{8}\ yd=\frac{31}{8}\ yd$

The length of the room = $1\frac{5}{4}\ yd=\frac{21}{4}\ yd$

The area of the rectangular room= $length \times width$

⇒The area of the rectangular room= $\frac{21}{4}\times\frac{31}{8}\ sq\ yd$

⇒The area of the rectangular room= $\frac{651}{32}\ sq\ yd$

⇒The area of the rectangular room= $20\frac{11}{32}\ sq\ yd$
