Find the product of (3.7 × 10^4) and 2.

a. 7.4 × 10^4
b. 0.74 × 10^4
c. 74 × 10^4
d. 7.4 × 10^3

i believe it is a though i'm not good with the ending (10^4 x 10^0, i believe), i think it is 4, but it could be 3. , ?

A
because 3.7 ×2 is 7.4. so the full answer would be 7.4 ×10^4

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
