Either. The perimeter of a square with area 1 square unit is 4, a rational value. The perimeter of a square with area 2 square unit is 4*sqrt(2), an irrational value.
The dimensions can be 4 units by 4 units
The absolute value of a complex number a+bi is the square root of (a2+b2). For example, the absolute value of 4+9i is the square root of (42 + 92) which is the square root of 97 which is about 9.8489 (The absolute value of a complex number is not complex.)
cos pi over four equals the square root of 2 over 2 This value can be found by looking at a unit circle. Cos indicates it is the x value of the point pi/4 which is (square root 2 over 2, square root 2 over 2)
The perimeter of a square is equal to 4 times the value of one side. So P = 4s 24 = 4s 24/4 = 4s/4 6= s The length of one side is 6 meters.
Either. The perimeter of a square with area 1 square unit is 4, a rational value. The perimeter of a square with area 2 square unit is 4*sqrt(2), an irrational value.
It is: 2

the value of pie=22/7, or 3.14, or 180. 4 pie= 4*22/7, or 3.142*4, or 180 *4. square of 4 pie= 7744/49, or 158.022, or 518400.
Yes. The letter i denotes the value of the "positive square root" of -1. So i² = -1. But also (-i)² = -1 as well. Remember that for every number there is a "positive" and "negative" square root. So if you want the square root of -4, you can do this: -4 = (-1)(4). So sqrt(-4) = sqrt[(-1)(4)] = sqrt(-1)*sqrt(4) = i*2 or -i*2. We usually write these as 2i and -2i.
Times it again by the same number [e.g] square of 4 is 4X4=16 so square of 4 is 16
Square root of 56 = Square root of (4 x 14) = (Square root of 4) x (Square root of 14) = 2 x (Square root of 14) The actual value would be 2 x 3.741 = 7.482
To 4 decimal places, it is -1.7321 and 1.7321
