Question

Algebraic models grade 12 math college please write the answers without explaining thank you.

Answer 1

From the problem :

$6^4\times6^{-5}$

In multiplying expressions with the same bases, the exponent will be added accordingly.

For example :

$a^m\times a^n=a^{m+n}$

the exponent of a are m and n, and the product will be a raised to the sum of m and n.

Applying this to the problem, we have :

$6^4\times6^{-5}=6^{4-5}=6^{-1}$

The answer is d. 6^-1
