(1/2)x^5/2 + (1/2)x^-1/2 = x^4/2
[(x^3)+1]² = (x^5)+1
[t^3]² = t^5
these correct?
Hello, maybnxtseasn!
I hope this is a True/False quiz . . . and not your work!
$\displaystyle (1)\;\tfrac{1}{2}x^{\frac{5}{2}} + \tfrac{1}{2}x^{-\frac{1}{2}} \:=\: x^{\frac{4}{2}}$
$\displaystyle (2)\; [(x^3)+1]^2 \:=\: x^5+1$
$\displaystyle (3)\;[t^3]^2 \:=\: t^5$
All of them are wrong . . .
