Answer:

3n\cdot 3n.

Step-by-step explanation:

We have been given an expression (3n)^2. We are asked to write our given expression without exponents.

Since 3n is raised to second power, this means that 3n is multiplied by itself.

(3n)^2=3n\cdot 3n

Therefore, our required expression would be 3n\cdot 3n.

How would you solve this problem?<br><br> ((2x^12y^3)/(x^10y))^-5
Hatshy [7]
There is no equals sign. Are we looking for x, or y?

Either way, with the -5 exponent outside the parentheses, you can multiply that to each exponent in the fraction to get rid of it.

I'm not sure what you mean by 2x^12y^3. Is it an exponent within another exponent?

Georgia [21]
The two expressions are equivalent because the associative property of multiplication is applied, which means that no matter where you put the parenthesis, the two expressions will still be equal.
