That verbal expression would read: 3(x+y)^2 + 5(2x -y)
^2 means 'squared' in the above example.
3x2 can be called "three times x squared", "three x squared", or "three times x to the power of two".
Three times the difference of a and m divided by twice their sum is equal to 6(a squared - m squared). 3(a - m)/2(a + m)

(3y2)4*3y2*3y2*3y2*3y2 = 38*y16 = 6561y16
16 to the 4th power, or 16 x 16 x 16 x 16 = 65,536

3x2 can be called "three times x squared", "three x squared", or "three times x to the power of two".
It is "a squared minus eighteen b".
Write an algebraic expression for the verbal expression. q squared minus 2 times q
Three times the difference of a and m divided by twice their sum is equal to 6(a squared - m squared). 3(a - m)/2(a + m)

36 squared times 24 squared is equal to 746,496.
Let n be the number. Then it's 3(n2 - 82).
The difference is that they are both totally different things. When you times something by two you're just doubling it and when you square something you times it by itself. Ex: 1x2=2 2x2=4 3x2=6 These are all doubling. Ex:1 squared is the same as 1x1 2 squared is the same as 2x2 3 squared is the same as 3x3 These are all numbers squared
yes
(3y2)4*3y2*3y2*3y2*3y2 = 38*y16 = 6561y16
2 centimeters is just 2 centimeters, and 2 centimeters squared is 4 centimeters. 2 centimeters x 2 centimeters = 4 centimeters squared = times 2
