The square root is #root(2)n# (usually denoted #sqrtx#), the third (or cube) root is #root(3)n#, the fourth root is #root(4)n# and so on. \( \Large \sqrt{15^{2} \times 12 \div (9) -125 + 21} = ? Find a perfect square that is a multiple of 18: in this case it would be 9, because 9 x 2 = 18. How do you multiply #(sqrt(a) +sqrt(b))(sqrt(a)-sqrt(b))#? Raman's present age is three times his daughter's present age, and nine-thirteenth of his mother's present age. write the expression as a sum or difference of logarithms. Both   i   and   -i   are the square roots of   -1 Since a square root has two values, one positive and the other negative   x2 + 5x + 25 = 0   has two solutions:  x = -5/2 + â 75/4 â¢  i    or  x = -5/2 - â 75/4 â¢  i Note that  â 75/4 can be written as  â 75  / â 4   which is â 75  / 2. The prime factorization of  75   is   3â¢5â¢5  To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. So, you can take a 3 out of the sqrt., because 3^2 is 9. precalculus. Solve your math problems using our free math solver with step-by-step solutions. Equations : Tiger Algebra gives you not only the answers, but also the complete step by step method for solving your equations x^3=125 so that you understand better I have heard many students read #root(3)n# as "the third square root of n".

What is the following sum? 1.2     Factoring  x2 + 5x + 25  The first term is,  x2  its coefficient is  1 .The middle term is,  +5x  its coefficient is  5 .The last term, "the constant", is  +25 Step-1 : Multiply the coefficient of the first term by the constant   1 â¢ 25 = 25 Step-2 : Find two factors of  25  whose sum equals the coefficient of the middle term, which is   5 . Answers Mine. It satisfies   i2  =-1. Conclusion : Trinomial can not be factored. Formula. 2.5     Solving    x2+5x+25 = 0 by the Quadratic Formula . Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :                      x^3-(125)=0, 1.1      Factoring:  x3-125  Theory : A difference of two perfect cubes,  a3 - b3 can be factored into              (a-b) â¢ (a2 +ab +b2)Proof :  (a-b)â¢(a2+ab+b2) =            a3+a2b+ab2-ba2-b2a-b3 =            a3+(a2b-ba2)+(ab2-b2a)-b3 =            a3+0+0+b3 =            a3+b3Check :  125  is the cube of   5 Check :  x3 is the cube of   x1Factorization is :             (x - 5)  â¢  (x2 + 5x + 25).
