How do you solve this problem what is the value of the expression 2x squared plus 3xy - 4y squared when x equals 2 and Y equals 4?
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
What is 4 sqaured?
4 squared is 16. 4 squared means that 4 is used as a factor 2 times. 4x4=16
What is a squared number in math?
A squared number is the product of an integer times itself. So, 16 is a squared number. 4 * 4 = 16.
How do you work out numbers squared?
A number squared is just that number times itself. For example four squared is four times four equals sixteen (42 = 4 x 4 = 16).
What is 4 to the second power times 4 to the second power times 4 to the second power?
4,096 or 4 to the sixth power. When multiplying numbers with powers you add the powers if the whole number is identical. 4 squared x 4 squared is 64, x 4 squared is 4096
What is 4 squared times 4 squared times 4 squared times 4 squared?
16 to the 4th power, or 16 x 16 x 16 x 16 = 65,536
What does 3.14 times 25 times 4 equal?

What is the formula for 3 squared plus 4 squared?
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
How many gallons of water are in a round pool that is 4 feet deep and 20 feet across?
Area of base times height. 3.14 times r which is 10 squared times the 4 feet deep. which is 3.14 times 10 squared which is 314 now times the height of 4ft deep. which is 1,256ft3 and 1 cubic ft is 7.48 gals. so multiply 1,256 and 7.48 to get 9,395 gals
What is a squared times a squared?
I believe A2 times A2=A4 (A to the power of 4).
Why is brayani wrong when she says when x equals 3 the value of 4x squared is 36?
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.
What is minus 3 squared times 4 squared?
-144
What is 4 times 4 squared?

What equals two squared?
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
How do you solve this problem what is the value of the expression 2x squared plus 3xy - 4y squared when x equals 2 and Y equals 4?
