Question

1)

What is the mathematical relationship between a^n and a^-n ? Explain

2) A positive exponent shows repeated multiplication . What repeated operation does a negative exponent show ?

I really need your help ! Thanks

Answer 1

A negative exponent (-n) just means that your base (a) is on the wrong side of the fraction bar meaning you would need to flip it to the other side. For example; if you have to write 2x^-3 using only positive exponents. you have 2x^-3/1 so you would have to move the negative exponent to the bottom which gives you 2/1x^3.

make sense?
