The result of $4^{0\ }$  is

• 0

• 1

• undefined

• Math error

When you have negative exponents, you should

• Flip over and change the sign of the base

• Flip over and change the sign of the exponent

• Multiply by the same number to get an exponent 0

• Divide by the base and then simplify using the exponents properties

Two sentences are true, choose them

• We get negative exponents because the multiplications are using integers and integers involve positive and negative numbers.

• We get negative exponents because we can have powers in the denominator.

• $\left(2^3\right)^3\times2^4\div2^8=2^5$

• $\left(2^3\right)^3\times2^4\div2^8=2^2$

Express, as integer or fraction, the answer of $500\times10^{-3}$
