Question 7

Which equation is equivalent to log3(2x4 + 8x3) – 3log3x = 2log3x?

Revolt · Accepted Answer

log3(2x + 8) = log3x2

Question 8

Order the steps to solve the equation log3(x + 2) = log3(2x2 − 1) from 1 to 6. 0 = (2x − 3)(x + 1) 0 = 2x2 − x −3 Potential solutions are −1 and 32. 2x − 3 = 0 or x + 1 = 0 x + 2 = 2x2 − 1 3log3(x + 2) = 3log3(2x2 − 1)
