Solve for x if 3√x2+3√x−20=0. Solve for x if 3√x2+3√x−20=0. A. 64 C. 48 B. 144 D. 728 Solution Click here to… Jhun Vert Fri, 06/07/2024 - 19:09 Solution Click here to expand or collapse this section Use the CALC function X = 64 will result to zero Answer: x = 64 Another Solution 3√x2+3√x−20=0 (3√x)2+3√x−20=0 Let z=3√x z2+z−20=0 z=4 and −5 For z = 4 4=3√x x=64 Check: 3√642+3√64−20=0 ← okay! For z = -5 −5=3√x x=−125 Check: 3√(−125)2+3√−125−20=0 ← okay! Answer: x = 64 and x = -125 Log in or register to post comments Log in or register to post comments
