Question

Write the expression using positive exponents. 4º.4-11

Answer 1

We want to calculate the following expression

`4^0\cdot4^{\text{ -11}}`

To do this, we will use the following properties of exponentiation.

We given a non zero number a, we have the following property

`a^b\cdot a^c=a^(b+c)`

In our case, we have a=4, b =0 anc c=-11. So we have

`4^0\cdot4^{\text{ -11}}=4^{0\text{ -11}}=4^{\text{ -11}}`

Now, to write this number with a positive exponent
