x=3 work out the value of 4x squared
4x^2 = 4 * 3^2 = 4 * 9 = 36
or, (4x)^2 = 12^2 = 144
To find the value of 4x squared when x = 3, you can follow these steps:
Step 1: Square the value of x.
3 squared = 3 * 3 = 9
Step 2: Multiply the squared value by 4.
4 * 9 = 36
Therefore, when x = 3, the value of 4x squared is 36.
To find the value of 4x squared when x = 3, we need to substitute the value of x into the equation and then simplify.
Firstly, let's substitute the value of x into the equation:
4x squared = 4 * (3) squared
Next, we square the value of 3:
4 * 3 squared = 4 * 9
Now, we multiply 4 by 9:
4 * 9 = 36
Therefore, the value of 4x squared when x = 3 is 36.
