16 to the 4th power, or 16 x 16 x 16 x 16 = 65,536
9 plus 16=25 3 squared is the same as 3 times three and 4 squared is the same as 4 times 4 3 times 3 + 4 times 4 9 plus 16 = 25
I believe A2 times A2=A4 (A to the power of 4).
She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.

The number times itself. For example 2 squared = 2x2=4 so 2 squared =4
Assuming the thing is as written and there are no brackets missed out then it is just 4 squared times 3 = 16x3=48.
4 squared means multiplied by itself so 2 squared is 2 times 2 which is 4 if i took 7 squared, that would be 7 times 7 which is 49
x = 2 so x squared = 4 and 2x squared = 2 times 4 = 8; y = 4 so xy = 2 times 4 = 8 and 3xy = 3 times 8 = 24; y squared = 4 times 4 = 16 and 4y squared = 4 times 16 = 64; so 8 + 24 - 64 = 32 - 64 = -32
(3y2)4*3y2*3y2*3y2*3y2 = 38*y16 = 6561y16
the answer is 32 metres squared. you times 8 by 4 metres and its 32 squared metres.
