(Laws of Exponents with Integer Exponents)

Choose the expression that is equivalent to [tex]$\frac{6^{-10}}{\left(6^4\right)\left(6^0\right)}$[/tex]:

A. [tex]-6^{14}[/tex]

B. [tex]-\frac{1}{6^{14}}[/tex]

C. [tex]6^{14}[/tex]

D. [tex]\frac{1}{6^{14}}[/tex]



Answer :

To solve the given expression [tex]\(\frac{6^{-10}}{6^4 \cdot 6^0}\)[/tex] by applying the laws of exponents, we can follow these steps:

1. Understand the Expression: The expression given is [tex]\(\frac{6^{-10}}{6^4 \cdot 6^0}\)[/tex].

2. Simplify the Denominator: According to the exponent law [tex]\(a^m \cdot a^n = a^{m+n}\)[/tex], we can add the exponents in the denominator:
[tex]\[ 6^4 \cdot 6^0 = 6^{4+0} = 6^4 \][/tex]
So, the expression becomes:
[tex]\[ \frac{6^{-10}}{6^4} \][/tex]

3. Apply the Quotient of Powers Rule: According to the exponent law [tex]\(\frac{a^m}{a^n} = a^{m-n}\)[/tex], we subtract the exponent in the denominator from the exponent in the numerator:
[tex]\[ \frac{6^{-10}}{6^4} = 6^{-10-4} = 6^{-14} \][/tex]

4. Rewrite Negative Exponents: According to the exponent law [tex]\(a^{-n} = \frac{1}{a^n}\)[/tex], a negative exponent can be rewritten as the reciprocal of the base with the positive exponent:
[tex]\[ 6^{-14} = \frac{1}{6^{14}} \][/tex]

Therefore, the expression equivalent to [tex]\(\frac{6^{-10}}{6^4 \cdot 6^0}\)[/tex] is [tex]\(\frac{1}{6^{14}}\)[/tex].

Among the given choices, the correct answer is:

[tex]\[ \boxed{\frac{1}{6^{14}}} \][/tex]
