Which expressions are equivalent to 3^4 • 3^x ? There is more than one way to skin a cat...okay gross analogy but it is just a saying...and I'm just sayin'.
Let's use the MathPapa calculator to figure it out.
Plug in your options. You want to know if one formula equals another, so put the one in first you are measuring the others against and add your equal sign, then add the possible options. The calculator will tell you if they are equivalent.
Your first option is (3 * x)^4.
Is 3^4 * 3^x = to 81x^4? Yep.
And so is 3^(4+x)
So your answers are B and E, if you're looking at what I think you are looking at...
Be smart. Pass math. You got this.
