Match each value to what it represents.
Serhud [2]

Answer:

Step-by-step explanation:

(5^3/2)^-2/3 = 0.2 ⇒ E

(256^0.5)^1.25 = 32 ⇒ C

(81^1/6)^3/2 = 3 ⇒ F

(1024^0.03)^20 = 64 ⇒ D

(1000^4/7)^7/3 = 10,000 ⇒ B

(49^5/2)^0.2 = 7 ⇒ A

Step-by-step explanation:

* Lets explain how to solve the problem

- If we have base x to a power n and all to the power of m then we

multiply the two powers to be one power on the base

- [(x^n)^m] = x^(nm)

* Lets solve the problem

∵

∴ (5^3/2)^-2/3 = 0.2 ⇒ E

∵

∵ 256 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2^8

∴

∴ (256^0.5)^1.25 = 32 ⇒ C

∵

∵ 81 = 3 × 3 × 3 × 3 = 3^4

∴

∴ (81^1/6)^3/2 = 3 ⇒ F (answer F must be 3 not 0.333)

∵

∵ 1024 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2^10

∴

∴ (1024^0.03)^20 = 64 ⇒ D

∵

∵ 1000 = 10 × 10 × 10 = 10³

∴

∴ (1000^4/7)^7/3 = 10,000 ⇒ B

∵

∴ (49^5/2)^0.2 = 7 ⇒ A

astraxan [27]
\frac{3}{x} -3 = \frac{x}{x}  -  \frac{3}{2}
3 -3x = x - \frac{3x}{2}
-6x -2x -x = 6
-9x=6
