Write [tex]\(\left(3^6 \times 3^5\right) \div 3^7\)[/tex] in the form [tex]\(n : 1\)[/tex] where [tex]\(n\)[/tex] is an integer.



Answer :

Certainly! Let's write [tex]\( \left(3^6 \times 3^5\right) \div 3^7 \)[/tex] in the form [tex]\( n:1 \)[/tex], where [tex]\( n \)[/tex] is an integer.

To do this, we will use the properties of exponents. Specifically, we will use the property that states [tex]\( a^m \times a^n = a^{m+n} \)[/tex] and the property that [tex]\( \frac{a^m}{a^n} = a^{m-n} \)[/tex].

1. Combine the product of the exponents:
[tex]\[ 3^6 \times 3^5 \][/tex]
According to the exponent multiplication property:
[tex]\[ 3^6 \times 3^5 = 3^{6+5} = 3^{11} \][/tex]

2. Now carry out the division with the exponent of the base 3:
[tex]\[ \frac{3^{11}}{3^7} \][/tex]
According to the exponent division property:
[tex]\[ \frac{3^{11}}{3^7} = 3^{11-7} = 3^4 \][/tex]

3. Express the result in the required form [tex]\( n:1 \)[/tex]:
[tex]\[ 3^4 = 81 \][/tex]

Thus, in the required form [tex]\( n:1 \)[/tex]:
[tex]\[ 81:1 \][/tex]

So, [tex]\( n = 81 \)[/tex], the integer value we need.
