Y=log x If y=10, then what is x?

Answer 1

The answer: x = 10¹⁰ = 10,000,000,000 ↔ (ten billion).

Answer 2

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)`
