2. Express each of the following as a rational number in the form of p/q<br> Where q≠0

ANTONII [103]

Step-by-step explanation:

We need to find each of the following as a rational number in the form of p/q

(a) (3/7)² (b) (7/9)³ (c) (-2/3)⁴

Solution,

(a) (3/7)²

$(\dfrac{3}{7})^2=\dfrac{9}{49}$

(b) (7/9)³

$(\dfrac{7}{9})^3=\dfrac{7\times 7\times 7}{9\times 9\times 9}\\\\=\dfrac{343}{729}$

$(\dfrac{-2}{3})^4=\dfrac{-2\times -2\times -2\times -2}{3\times 3\times 3\times 3}\\\\=\dfrac{16}{81}$

Hence, this is the required solution.

-2(4х + 4) — 3х – 2 = 34<br> Find x

djverab [1.8K]

Answer:

x = -4

Step-by-step explanation:

Distribute the -2 into the parentheses and your equation becomes -8x - 8 - 3x - 2 = 34

Then combine the -8x and -3x as well as the -8 and -2 to have -11x - 10 = 34

Add 10 to both sides and get -11x = 44

Divide both sides by -11 for x=-4
