yes please! just learn them two days ago

Answer 4

what is it turn to? 3-2=9^x?

Answer 5

that the formula, log (base a) b = c means a^c =b

Answer 6

your a is 3 (base 3) your c is -2 (the whole log =-2), your b is 9^x

Answer 7

oh okay i just didn't see what it turns to

Answer 8

now, right side is 9^x = 3^2x is it ok?

Answer 9

left side 3^-2 = 3^2x ---> 2x =-2 --> x =-1. is it ok?

Answer 10
