Anyone here a math genius?
A friend on facebook posted this problem from her son's 6th grade math. I'm clearly an idiot, cause I can't figure it out.
If y*=3y-1, then what is 3*+5? Seems to me that you have to solve for the y and also for the exponent, but I can't figure out how. |

Is y* supposed to be y^x where x is a variable?

yeah what was said above, the way you got it typed doesn't make sense and it's like his teacher made shit up. * is generally thought of as multiplication.

I dont think that was copied right, if solve for x you get a complex number.

yep, there is some math in there that is not 6th grade level, i think there is some missing info that the teacher gave. I don't remember logarithms that early.
