Question

(4*10^3)(2*10^6)

Answer 1

(4*2) (10^(6+3))

8 * 10^9

Answer 2

I see, it's that easy?

Answer 3

easy as cake.

Answer 4

lol...ok what about(3.5*10^3)(5.1*10^-5)?

Answer 5

is it 17.85*10^-15?

Answer 6

or u can do like \[(40)^{3}(20)^{6}\]

Answer 7

but I'm supposed to answer in scientific notation...

Answer 8

sure it will be 409,600,000,000 and in SF it will look like 4.096x10^12

Answer 9

\[3.5\times10^3\times5.1\times10^{-5}=17.85\times 10^{-2}=1.785 \times 10^{-1}\]

Answer 10

And do not pay any attention to sna. 4X10^3 IS NOT the same as 40^3

Answer 11

thank you. how do you divide scientific notation? for example: 2.1*10^6 / 1.5*10^-3

Answer 12

\[4\times10^3=4000 while (40)^3=64000\]

Answer 13

Divide the numbers and subtract the exponents.

Answer 14

is it 1.4*10^3?

Answer 15

2.1/1.5=1.4
6-(-3)=9
So the result is 1.4 x 10^9

Answer 16

oh I see where I went wrong

Answer 17

so would 1.0*10^4 / 2.0*10^6 = .5*10^-2?
