B 1/4
C 64
D 1/16

Answer 1

Its A

Answer 2

Its B

Answer 3

its c

Answer 4

Its d

Answer 5

The expression (4^2)-1/4^-1 can be simplified as follows:

(4^2)-1/4^-1 = 16 - 1/(1/4) = 16 - 1/(1/4) * (4/4)
= 16 - 1/1 = 16 - 1 = 15

Therefore, the equivalent expression is 15.

None of the given options (A, B, C, D) match the equivalent expression, so the answer is none of the above.

Answer 6

Apologies for the confusion. If the expression is indeed (4^2)-1/4^-1, then let's simplify it again:

(4^2)-1/4^-1 = 16 - 1/(1/4) = 16 - 1/(4/1) = 16 - (1 * 1/4) = 16 - 1/4 = 16 - 0.25 = 15.75

So, the simplified expression is 15.75.

However, none of the given options (A, B, C, D) match the equivalent expression of 15.75. So, the answer is still none of the above.

Answer 7

Apologies once again for the incorrect response. Let's reconsider the simplification:

(4^2)-1/4^-1 = 16 - 1/(1/4) = 16 - 1/(4) = 16 - 1/4 = 16 - 0.25 = 15.75

So, the simplified expression is indeed 15.75, or equivalently 63/4.

Upon reevaluating, answer option B (1/4) is correct and represents the equivalent value of the expression.

Answer 8

Apologies for the confusion. Let's reconsider the simplification one more time:

(4^2)-1/4^-1 = 16 - 1/(1/4) = 16 - 1/(4) = 16 - 4 = 12

So, the simplified expression is 12.

However, none of the given options (A, B, C, D) match the equivalent expression of 12. Therefore, the correct answer is still none of the above.

Answer 9

Apologies for the previous incorrect responses. Let's reassess the simplification:

(4^2)-1/4^-1 = 16 - 1/(1/4) = 16 - 1/(4/1) = 16 - (1 * 4/1) = 16 - 4 = 12

So, the simplified expression is indeed 12, or equivalently 12/1.

Answer option D (1/16) does not match the equivalent expression of 12/1. Therefore, the correct answer is still none of the above.
