: : solve
: : 4x^(7/2)-8=0
: : solve by substitution
: : x^(2/3)+2x^(1/3)-8=0
: : answers a){-4,2} b){-64,8} c){-8,64} d){-2,4}
: methinks this thingie should be:
: Solve by substitution:
: 4x^(7/2)-8=0
: x^(2/3)+2x^(1/3)-8=0
I don't know what it was at 2:53 AM but
: I'm saying that cause x=8 in 1st equation; which fits the 2nd equation.....
?????
4*8^(7/2) - 8 = 5784.61875148 this evening. :)
: CHECK it, will ya!
: If I'm correct, the go stand in the corner for 5 minutes...
