The missing number in the simplified exponential expression is -7.
To solve for it, we can rewrite the equation as (7^x) / (7^5) = 7^12, where x represents the missing exponent.
Next, we can simplify the left side of the equation by applying the rule of exponentiation (a^m / a^n = a^(m-n)).
This gives us 7^(x-5) = 7^12.
Since the bases are the same, the exponents must be equal.
Therefore, x - 5 = 12.
By solving this equation, we find that x = 17.
Therefore, the missing number in the simplified exponential expression is 17.
What is the missing number in this simplified exponential expression: 7^?-:7^5=7^12 ? (1 point)
