5-131.

Consider 3^{log}_{3}*x*

First consider just the exponent: It can be translated as '3 to the power of something that makes 3 become *x*.'

Now consider the entire expression: 3 is being raised to that 'something' that makes 3 become *x*...

Consequently, the expression = *x*.

One way: 9 = 3^{log}_{3}*9*

Find another way.

Refer to previous hints.

One way: 7 = 7^{??????}
