Question

If 10^x=3, find the value of 10^(2x+1).

Answer 1

log(3)=x, so 10^(2log(3)+1) would be your answer
you can further simplify to 10^(log(9)+1)

Answer 2

Can't it be solved without using log?

Answer 3

Switching from exponential to logarithmic is the easiest way to find solutions to these types of problems.

Answer 4

But we are required to ude exponential method.

Answer 5

10^(2x+1) = 10^(2x) * 10^(1) = (10^x)^2 * 10.

Answer 6

*use
