Question

The value of $5^0\times 5^0\times 5^0\times 5^0\times \left(5^0-5^0\right)$ is ___________

Answer 1

By the law of exponent,

$a^0=1$.

So, $5^0=1$.

Thus, $5^0\times 5^0\times 5^0\times 5^0\times \left(5^0-5^0\right)$$=1\times 1\times 1\times 1\times \left(1-1\right)$

$=1\times 0$

$=0$.

Therefore, the value of $5^0\times 5^0\times 5^0\times 5^0\times \left(5^0-5^0\right)$ is $0$.
