Answer:
45,300
Explanation:
45.3 · 10^3
Let's solve 10^3:
10 x 10 x 10
= 1000
Now let's multiply it with 45.3 since that was what we were originally doing:
45.3 · 1000
(move the decimal three digits over because whenever you multiply a number by a base of 10 with a power of anything, you move that many exponents over. In this case, the exponent is 3, so move the decimal 3 digits over.)
= 45,300
