This encounters adding, subtracting and finding the least typical multiple.
You are watching: X^(3/2)
Step by action Solution
Rearrange:Rearrange the equation by subtracting what is to the ideal of the equal authorize from both political parties of the equation : x^3/2-(1/8)=0
Step by step solution :
Step 1 :
1 leveling — 8Equation at the finish of step 1 : (x3) 1 ———— - — = 0 2 8
action 2 :x3 simplify —— 2 Equation at the end of action 2 : x3 1 —— - — = 0 2 8
Step 3 :Calculating the Least usual Multiple :3.1 discover the Least usual Multiple The left denominator is : 2 The ideal denominator is : 8
|Product that allPrime Factors||2||8||8|
Least usual Multiple: 8Calculating multiplier :
3.2 calculate multipliers because that the 2 fractions denote the Least usual Multiple by L.C.M denote the Left Multiplier through Left_M represent the ideal Multiplier by Right_M represent the Left Deniminator through L_Deno signify the ideal Multiplier by R_DenoLeft_M=L.C.M/L_Deno=4Right_M=L.C.M/R_Deno=1Making equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractionsTwo fountain are called equivalent if they have the exact same numeric value. For example : 1/2 and 2/4 space equivalent, y/(y+1)2 and also (y2+y)/(y+1)3 are identical as well. To calculate equivalent portion , multiply the numerator of every fraction, by its respective Multiplier.
L. Mult. • L. Num. X3 • 4 —————————————————— = —————— L.C.M 8 R. Mult. • R. Num. 1 —————————————————— = — L.C.M 8Adding fountain that have a common denominator :3.4 including up the two indistinguishable fractions include the two identical fractions which now have a usual denominatorCombine the molecule together, put the amount or difference over the usual denominator then alleviate to lowest state if possible:
x3 • 4 - (1) 4x3 - 1 ———————————— = ——————— 8 8 trying to factor as a difference of Cubes:3.5 Factoring: 4x3 - 1 concept : A distinction of 2 perfect cubes, a3-b3 have the right to be factored into(a-b)•(a2+ab+b2)Proof:(a-b)•(a2+ab+b2)=a3+a2b+ab2-ba2-b2a-b3 =a3+(a2b-ba2)+(ab2-b2a)-b3=a3+0+0-b3=a3-b3Check: 4 is not a cube !! Ruling:Binomial have the right to not be factored together the distinction of two perfect cubes
Polynomial root Calculator :3.6 find roots (zeroes) the : F(x) = 4x3 - 1Polynomial root Calculator is a collection of approaches aimed in ~ finding values ofxfor i m sorry F(x)=0 Rational root Test is just one of the over mentioned tools. It would only discover Rational Roots the is number x which have the right to be expressed as the quotient of 2 integersThe Rational source Theorem states that if a polynomial zeroes because that a reasonable numberP/Q then ns is a factor of the Trailing consistent and Q is a factor of the leading CoefficientIn this case, the top Coefficient is 4 and also the Trailing consistent is -1.

Equation in ~ the end of action 3 : 4x3 - 1 ——————— = 0 8
Step 4 :When a portion equals zero :4.1 as soon as a portion equals zero ...Where a portion equals zero, that numerator, the component which is above the portion line, need to equal zero.Now,to remove the denominator, Tiger multiplys both sides of the equation by the denominator.Here"s how:
4x3-1 ————— • 8 = 0 • 8 8 Now, on the left hand side, the 8 cancels out the denominator, while, top top the best hand side, zero time anything is quiet zero.The equation now takes the shape:4x3-1=0
Solving a solitary Variable Equation:4.2Solve:4x3-1 = 0Add 1 come both political parties of the equation:4x3 = 1 divide both sides of the equation by 4:x3 = 1/4 = 0.250 when two things space equal, their cube roots are equal. Taking the cube source of the two sides the the equation us get: x = ∛ 1/4 The equation has one actual solutionThis solution is x = ∛ 0.250 = 0.62996
