The square root of 28 in simplified radical form is...2 * Square root of 7
irrational
To find the square root of the expression (2 \times 2 \times 5 \times 7 \times 7 \times 5), first simplify it by grouping the factors: ( (2^2) \times (5^2) \times (7^2) ). The square root of a product can be calculated by taking the square root of each factor. Thus, the square root of (2^2 \times 5^2 \times 7^2) is (2 \times 5 \times 7 = 70).
The square root of 4 is 2, if you multiply that by the square root of 49, which is 7, you get 14.

x + y = -7xy = -15y = -x - 7x(-x - 7) = -15-x^2 - 7x = -15 multiplying both sides by -1x^2 + 7x = 15 complete the square;(x^2 + 7x + 49/4) = 15 + 49/4(x + 7/2)^2 = 109/4(x + 7/2) = (plus & minus)square root of 109/41. x = -7/2 + (square root of 109)/22. x = -7/2 - (square root of 109)/2y = -x - 7y = -[-7/2 + (square root of 109)/2] - 7 = 7/2 - (square root of 109)/2 - 71. y = -7/2 - (square root of 109)/2 ory = -x - 7y = -[-7/2 - (square root of 109)/2] - 7 = 7/2 + (square root of 109)/2 - 72. y = -7/2 + (square root of 109)/2 Check it:

sqrt(98) = sqrt( 2 x 49(_ = sqrt(2) X sqrt(49) = sqrt(2) X 7 usually written as 7sqrt(2) (Surd form) Numerically the answer is 9,899494937.....
Do the multiplication, then take the square root. After the multiplication, you get 28x4y2. The square root of 28 is 2 times the root of 7, the square root of x4 is x2, and the root of y2 is y. So, the final result is 2 times square root of 7, times x2y.
it is 14.
