Y=log x If y=10, then what is x?
Assuming we're working with the base 10 log, you can solve by making both sides exponents to a base of 10 (which cancels the log on the right side):
\(10=log x \\ 10^{10}=10^{logx} \\ x = 10^{10}\)
The answer: x = 10¹⁰ = 10,000,000,000 ↔ (ten billion).

log x = y ↔ log₁₀ x = y ; ↔ log₁₀ x = 10 ; ↔ x = 10¹⁰ ;

→ x = 10¹⁰ = 10,000,000,000 ↔ (ten billion).
