Question from celina, a student: what is the exponential form of 4x*4x |
Hi Celina,
Exponential form means using exponents and there are a variety of ways you can write this expression using exponents.
4x * 4x = 4 * x * 4 * x = 4 * 4 * x * x = 42 * x2 = 42 x2.
But 42 = 16 so you might write this as
4x * 4x = 16 x2.
Also 22 = 4 so you could write this as
4x * 4x = 22x * 22x = 22 * 22 * x2 = 24 x2.
I'm not sure which form is expected, they are all exponential forms.
