Answer:

D. ∛4a^2 / a

Step-by-step explanation:

∛4a / ∛a^2

= ∛(4a)* ∛a / ∛a^2 * ∛a

= ∛4a^2 / ∛a^3

= ∛4a^2 / a

Answer is D. ∛4a^2 / a

Answer:

d 4 ^1/3 a^2/3

------------

Step-by-step explanation:

(4a) ^ 1/3

----------------

( a^2) ^ 1/3

We know that (bc)^d = b^d * c^d and m^n^p = m^(n+p)

(4) ^ 1/3 * (a) ^ 1/3

----------------

( a) ^(2* 1/3)

(4) ^ 1/3 * (a) ^ 1/3

----------------

( a) ^(2/3)

We know that when we divide powers with the same base, we subtract the exponents

(4) ^ 1/3 * (a) ^ (1/3 - 2/3)

4 ^ (1/3) * a ^ -1/3

4 ^1/3

------------

a^ 1/3

We can multiply the top and bottom by a^2/3

4 ^1/3 a^2/3

------------

a^ 1/3 * a^2/3

4 ^1/3 a^2/3

------------

Prajna is listing squares of two-digit numbers in such a way that the digit in their units place is 6.

dem82 [27]

Answer:

2 (option B)

Question:

Prajna is listing squares of two-digit numbers in such a way that the digit in their units place is 6.

How many numbers should he have listed?

a) 9 b) 2 c)18 d) 20

Step-by-step explanation:

We would find the perfect squares that are two digit numbers

For two digit perfect squares:

Largest two digit number= 81 = 9²

Smallest two digit number= 16 = 4²

Total Two digit number perfect squares = Highest number - lowest number + 1

= 9-4+1 = 6

There are 6 two digit perfect squares

Next, we have to find how many of them have 6 in their units place.

The rule to be applied: If a number has 4 or 6 in the unit place, then its square has 6 in the units place.

Following this, the possibilities are 4², 6².

We have two of such numbers.

Therefore, he would have listed 2 numbers.
