1. Let's simplify. sqrt4(64)*sqrt(4) = 8*2 = 16. sqrt(d)*sqrt(d^3) = sqrt(d^4) = d^2. sqrt(k) ... it ain't gettin' no simpler. just plain ol' sqrt(k). Putting everything together, you have... 16*d^2*sqrt(k).
2. √(64d) . √(4d^3 k) = √(64d . 4d^3 k) = √(256 d^4 k) = 16d² √ k Alejandra
3. 16d^2k^1\2
4. Hi, ..___....____ √64d √4d³k = ...________ √ 256 d^4k = ........_ 16d²√k <== ANSWER I hope that helps!! :-)
