3. Which inequalities show a correct relationship between expressions?

igomit [66]

Answer: a and d

Step-by-step explanation:

First of all, we need to make a analysis of each letters:

a. factoring 32 = 2.2.2.2.2 = $2^{5}$

$2^{5}^{3} = 2^{15}$

then,

16 = $2^{4}$

but $2^{4}^{4} =2^{16}$

in conclusion that, this inequality is correct

b. 27 = $3^{3}$

this first situation is equal to $3^{9}$

the second situation is:

81 = $3^{4}$

and $3^{4}^{4} = 3^{16}$

it's a mistake.

c. factoring 9: $9 = 3^{3}$

$3^{9}$ < $3^{5}$

it's wrong.

d. factoring 8 = $2^{3}$

factoring 32 = $2^{5}$

$2^{12}$ > $2^{10}$

This is true.

Finally.. our correct answers is a and d.
