lakkis [162]

Answer:

$10^5$

Step-by-step explanation:

Exponents are basically just saying how many times the number is multiplied by itself.

In the expression $10\cdot10\cdot10\cdot10\cdot10$ , we can see that 10 is being multiplied by itself 5 times.

So the exponent becomes 5, and the base is 10.

$10^5$ .
