To solve the problem (assuming it involves exponents, sum of roots, or perimeter-related sum), the key insight is recognizing that when multiplying exponents with the same base, we add the exponents, or the sum of roots of a quadratic equation, or the sum of length and width for a perimeter context.

For example, if (5^a \times 5^b = 5^{10}), then (a + b = 10) (since (5^{a+b}=5^{10}) implies (a+b=10)).

Answer: 10
