enable cube root of (-36+squareroot of-2800) = a and cube root of (-36 - squareroot -2800) = b and sum = -x (kindly word -x and not x ) -x = a + b so a+b+x = 0 from the above a^3 + b^3 + x^3 = 3abx a^3 = (-36+squareroot of-2800) b^3 = -36 - squareroot -2800) ab = cube root of((-36 + squareroot -2800)((-36 - squareroot -2800)) = cube root of(1296+2800) = sixteen so puttinng the vaue -seventy two + x^3 = 3*16x x^3-48x-seventy two = 0 you will possibly desire to be above to sove it for x = -6 as considered one of strategies

Put .36 into your calculator, then hit the ^ key and put the fraction 1/3.
Or, put in .36 and hit the y^x key and put in .33333333333

cube root of .36
= 0.36^1/3
= 0.36^0.3333333
= 0.71137 (approx)
