Answer :

Certainly! Let's solve the equation [tex]\( \frac{1}{7^{13}} = 7^x \)[/tex] step by step.

1. Understand the fraction: The left-hand side of the equation is a fraction which involves a power of 7. We have [tex]\( \frac{1}{7^{13}} \)[/tex].

2. Rewrite the fraction as a negative exponent: A useful property of exponents is that [tex]\( \frac{1}{a^b} = a^{-b} \)[/tex]. Using this property, we can rewrite [tex]\( \frac{1}{7^{13}} \)[/tex] as [tex]\( 7^{-13} \)[/tex].

So, the equation [tex]\( \frac{1}{7^{13}} = 7^x \)[/tex] can be rewritten as:
[tex]\[ 7^{-13} = 7^x \][/tex]

3. Equating the exponents: When the bases are the same, we can set the exponents equal to each other. Here, the base is 7 on both sides of the equation.

Therefore, we equate the exponents:
[tex]\[ -13 = x \][/tex]

Hence, the value of [tex]\( x \)[/tex] is [tex]\(-13\)[/tex].

Thus, [tex]\( x = -13 \)[/tex].
