Question

I need help on these questions here is an image

Answer 1

1.

`(-3\cdot4)^0`

As a rule, any value powered by zero equals 1, always

So the answer to this calculation is one

`(-3\cdot4)^0=1`

3) For this exercise the same rule as before applies:

`4x^0=1`

4) When you multiply two exponents that have the same base number, you have to add the exponents. In this case both base numbers are "x"

`x^(-8)\cdot x^4=x^(-8+4)=x^(-4)`
