sqrt (1/4) Using a simple observation, we got: =sqrt ( (1^2)/ (2^2)) Using the properties, (a^b)/ (c^b)= (a/c)^b. So, we got. =sqrt ( (1/2)^2) =+-1/2. Since we are talking about real numbers, we will only take the principal (positive) square root, and so the answer will be just 1/2. 1/2 We have: sqrt (1/4) Using a simple observation, we got ...

Finding the fourth root of a number is the opposite of multiplying a number by itself 4 times. In other words, it's the opposite of using an exponent of 4. Let's look at it mathematically. x4 = 256.

Answer link. 2 and -2 are square roots of 4. The principal square root of 4, (denoted sqrt4) is 2 A number is a square root of 4 is, when multiplied by itself, the result is 4. In notation: n is a square root of 4 if n^2 = n xx n = 4 There are two numbers that will work 2 xx 2 = 4 and also -2 xx -2 = 4 so the numbers 2 and -2 are square roots of 4.

For starters (x^2+4) > 0 for all x in RR, so it has no linear factors with real coefficients. Suppose you produced some formula f (x) for sqrt (x^2+4). Then f (1) = sqrt (5) and f (2) = sqrt (8) = 2 sqrt (2). So any such formula f (x) would involve square roots or fractional exponents or suchlike, and be as complex as the original sqrt (x^2+4)
