Question

I just need to know the which one is the answer out of (1-4) questions. Please help??

Answer 1

`{14}^( - 4) = \frac{1}{ {14}^(4) }`

Explanation:

To find the answer for this, you have to follow the negative rule of exponents.

That is,

1) If the number with a negative power is in it's numerator, the number with a negative exponent should be put to the denominator and make the power positive.

2) If the number with a negative power is in it's denominator, the number with a negative exponent should be put to the numerator and make the power positive.

Here, we have follow the rule 1.

Ex:

`{a}^( - n) = \frac{1}{ {a}^(n) }`

Accordingly, let us find the answer for the question.

`{14}^( - 4) = \frac{1}{ {14}^(4) }`

Answer 2

1/ 14^4

Explanation:

Rules of Exponents

We know that a^-b = 1/a^b

14^-4 = 1/ 14^4
