Express the sum in terms of summation notation. Note that (â4) × (â4) = 16 too, so â4 is also a square root of 16. The sum of cubes identity can be written: #a^3+b^3 = (a+b)(a^2-ab+b^2)# So we find: #x^6y^3+y^9 = y^3(x^6+y^6)# #color(white)(x^6y^3+y^9) = y^3((x^2)^3+(y^2)^3)# #color(white)(x^6y^3+y^9) = y^3(x^2+y^2)(x^4-x^2y^2+y^4)# Then note that: #(x^2-axy+y^2)(x^2+axy+y^2) = x^4+(2-a^2)x^2y^2+y^4# So putting #a=sqrt(3)# we find: "Squared" is often written as a little 2 like this: This says "4 Squared equals 16" (the little 2 means the number appears twice in multiplying, so 4×4=16). To sum integers from 1 to N, start by defining the largest integer to be summed as N. Don't forget that integers are always whole and positive numbers, so N can't be a decimal, fraction, or negative number. ; S(i) refers to sum of Fibonacci numbers till F(i).
