Answer:

Option a is correct.

2 = 1

Step-by-step explanation:

Using exponent rules:

\frac{1}{a^n} = a^{-n}

a^n \cdot a^m = a^{n+m}

Given the equation:

(\frac{1}{5000})^{2z} \cdot (5000)^{2z+2} = 5000

then;

(5000)^{-2z} \cdot (5000)^{2z+2} = 5000

Apply the exponent rules:

(5000)^{-2z+2z+2} = 5000

then;

(5000)^{-2z+2z+2} = (5000)^1

On comparing both sides we have;

-2z+2z+2 = 1

Combine like terms;

2 = 1

Therefore, the equation shows the result is, 2 = 1

Arrange the given steps in the correct order to find A and B if A and B are two sets where A – B = {1, 5, 7, 8}, B – A = {2, 10}
GarryVolchara [31]

Answer:

A = {1, 3, 5, 6, 7, 8, 9}

B = {2, 3, 6, 9, 10}

Step-by-step explanation:

Here as given in the question:

A – B = {1, 5, 7, 8}   ⇒ {1, 5, 7, 8} is in A not in B.

B – A = {2, 10} ⇒  {2, 10} is in B  not in A

A ∩ B = {3, 6, 9}   ⇒ {3, 6, 9} is BOTH in A and B.

Step 1:

Set A can also be expressed as :  A = (A - B) ∪ (A ∩ B)

Set A can also be expressed as :  B = (B - A) ∪ (A ∩ B)

Step 2:

Substituting the values of (A - B) and (B - A)

A = {1, 5, 7, 8} ∪ {3, 6, 9}

B = {2, 10} ∪ {3, 6, 9}.

Step 3:

Finding the UNION of the above two sets, we get:

A = {1, 3, 5, 6, 7, 8, 9}

B = {2, 3, 6, 9, 10}
