Question 316029
When you multiply by {{{10^4}}}, you're basically going to move the decimal point 4 spots to the right. So *[Tex \LARGE 4.1 \times 10^4 = 41000].



Similarly, multiplying by {{{10^3}}} moves the decimal point to the right 3 spots. So *[Tex \LARGE -1 \times 10^3 = -1000]. Note: -1 = -1.0



Altogether, we get *[Tex \LARGE 4.1 \times 10^4 -1 \times 10^3 = 41000-1000=40000]



So *[Tex \LARGE 4.1 \times 10^4 -1 \times 10^3 = 40000]
