Answer
$16x^{20}-32x^{15}+24x^{10}-8x^5+1$
Work Step by Step
Use the binomial theorem formula (detailed on page 754) to solve the problem. Be careful in writing each term correctly.
$(2x^5-1)^4$
$1*(2x^5)^4+4*(2x^5)^3*(-1)+6*(2x^5)^2*(-1)^2+4*(2x^5)*(-1)^3+(-1)^4$
$16x^{20}-32x^{15}+24x^{10}-8x^5+1$
