8=x^2-x^( 3/2)
8=x^(2-3/2)
8=x^(1/2)
8^2=x
x=64

hope it helps

yapyuanlipdcvui: answer is 4 you are wrong but thank you for trying

yapyuanlipdcvui: nvm la i ask my teacher or friend tomorrow

TheLostMonk: yes ANS is 4

TheLostMonk: here is solution ¶¶¶¶¶¶ 8=x^2-x^(3/2) ¶¶¶¶¶ 8=(√x-1)x^(3/2) ¶¶¶¶ take sqaure root both side ¶¶¶¶¶•••• 8^2 = [√x-1) x^(3/2)]^2 ¶¶¶¶¶¶ 64 =(√x- 1)^2 x^(3/2)^2. ¶¶¶¶¶. 64 = (√x -1)^2 x^3 ••••¶¶ now take minimum value of (√x - 1)^2 ,which is 1. ¶¶¶¶¶. hence. 64 = 1× x^3. ¶¶¶¶¶. 64 =x^3. ¶¶¶¶. this Implies that (4 )^3. = x^3. ¶¶¶¶¶¶ equalized Power will be cancelled to each other. so. x =4. hope now it helped you !!!

TheLostMonk: now answer is 4 .

yapyuanlipdcvui: thks bro~~
