(1.4 x 10^3)(2.5 x 10^-6)
I think you go (1.4 x 2.5)+(10^3 x 10^-6)

and then... i dont know XD help??

Answer 1

No No NO

Answer 2

Im obviously not very good at math XD

Answer 3

everything is still multiplied

Answer 4

ohhhhh

Answer 5

here is how we would so it we would do it
\[(1.4*2.5)(10^{3+(-6)})\]
Ok so we would multiply the 2 values but if you notice there are exponents with the same base. When multiplying exponents with the same base you keep the base and just add the exponents
So our base in this case is 10 and if you look above you can see that I just added the 2 exponents

Answer 6

Yeah it wouldn't be your answer of 3.5+10^-3 but 3.5*10^-3

Answer 7

So it would be 3.5 x 10^-3 ?

Answer 8

Ohhhh thats the full answer

Answer 9

Yes

Answer 10
