Answer:
Step-by-step explanation:
In exponential form, those look like this:
10⁵ × 10⁴
Those 10's are not just regular numbers, they're called bases. The rule for multiplying bases with exponents is that if you're multiplying like bases, you add the exponents. We do indeed have like bases, so we add the exponents 5 and 4 together (which is 9) so the solution to this simplification is 10⁹. If the bases are not like, this rule does not apply. In fact, no rule applies!!
