How are (3x)^2 and 3x^2 different?

(3x)^2=9x^2

(3x^2)=3x^2

Step-by-step explanation:

The difference between the two is that

(3x)^2 means the square applied to both the 3 and the x to give 9x^2

But on the other side

(3x^2) means that the square only applies to x without involving 3 which gives 3x^2

So there is difference between them

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2
