6^-5 x 6^?=6^10

Find the missing number

To find the missing number, we need to first simplify the left side of the equation.

6^-5 can be written as 1/6^5, since a negative exponent means taking the reciprocal.

So, the equation becomes:

(1/6^5) x 6^? = 6^10

Now, multiply the two terms on the left side:

(1/6^5) x 6^? = 1/6^(5-?) = 6^10

Since we want the bases to be equal, we can set the exponents equal to each other:

5 - ? = 10

Subtract 5 from both sides:

-? = 5

And multiply both sides by -1:

? = -5

Therefore, the missing number is -5.
