What is your score?
The 1. answer is (a) 1/2 not (b).27^x = 3^3x9 = 3^21/3^x = 3^(-x)so3^3x = 3^2 * 3^(-x)3^3x = 3^(2-x)3x = 2-x /+x4x = 2 /:4x = 2/4 = 1/2Just sayin'.
I quickly did this in my head (I'm a math teacher), got 1/2, saw their answer, did it again slowly, got 1/2 again. Stopped the quiz, they aren't even competent enough to do the first problem.
15 seconds my ass theres a pause button sucker. Im not cheating though
you can also pause the the video to solve the question

The 1. answer is (a) 1/2 not (b).
27^x = 3^3x
9 = 3^2
1/3^x = 3^(-x)
so
3^3x = 3^2 * 3^(-x)
3^3x = 3^(2-x)
3x = 2-x /+x
4x = 2 /:4
x = 2/4 = 1/2
Just sayin'.
