Question

X3/ y3 - 8
128 x3 -686
27 q3 /r3 + r3/q3
54x3 - 432y3
125 a3/ b3 + b3 125

Answer 1

STEP1:

a3 Simplify —— b3

Equation at the end of step1:

(x3) (q3) (r3) a3 ((((————-(8128•(x3)))-(68627•————))+(——————•(x3)))-((432•(y3125))•——))+b3125 (y3) (r3) (q354) b3

STEP 2 :

Equation at the end of step2:

(x3) (q3) (r3) a3 ((((————-(8128•(x3)))-(68627•————))+(——————•(x3)))-((24•33y3125)•——))+b3125 (y3) (r3) (q354) b3

STEP 3 :

r3 Simplify ———— q354

Equation at the end of step3:

(x3) (q3) r3 432y3125a3 ((((————-(8128•(x3)))-(68627•————))+(————•x3))-——————————)+b3125 (y3) (r3) q354 b3

STEP 4 :

q3 Simplify —— r3

Equation at the end of step4:

(x3) q3 x3r3 432y3125a3 ((((————-(8128•(x3)))-(68627•——))+————)-——————————)+b3125 (y3) r3 q354 b3

STEP 5 :

Equation at the end of step5:

(x3) 68627q3 x3r3 432y3125a3 ((((————-(26•127x3))-———————)+————)-——————————)+b3125 (y3) r3 q354 b3

STEP 6 :

x3 Simplify —— y3

Equation at the end of step6:

x3 68627q3 x3r3 432y3125a3 ((((—— - (26•127x3)) - ———————) + ————) - ——————————) + b3125 y3 r3 q354 b3

STEP7:Rewriting the whole as an Equivalent Fraction

 7.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  y3  as the denominator :

(26•127x3) (26•127x3) • y3 (26•127x3) = —————————— = ——————————————— 1 y3
