Video Solution

Solution Steps

00:00 Solve

00:02 According to the laws of exponents, any number(A) to the power of(-N)

00:05 equals 1 divided by the number(A) to the power of(N)

00:08 Let's apply in the question, the formula works from number to fraction and vice versa

00:11 The number 1 divided by (2) becomes 2

00:14 and the exponent (9) becomes (-9)

00:16 and this is the solution to the question

Step-by-Step Solution

We use the power property for a negative exponent:

$a^{-n}=\frac{1}{a^n}$ We apply it to the given expression:

$\frac{1}{2^9}=2^{-9}$

Therefore, the correct answer is option A.

Answer

$2^{-9}$
