anonymous · Answer

i got the answer. heres another question: $$3.5\times10^{8}\div7\times10^{4}$$

amistre64 · Answer

ok...

I see that 35/70 = 1/2  or .5   lets go with .5

.5 x 10^(8-4) = .5 (10^4)  to keep things in scietific notation, we should move the decimal till we get an integer like this:

5 (10^5)
