Question

8. (2 × 10^3)(4 × 10^–5)
A. 8 × 10^–2
B. 0.8 × 10^–2
C. 8 × 10^–1
D. 8 × 10^2

Answer 1

2*4*10^(3-5) gives answer

Answer 2

Is that x or a multiply sign

Answer 3

Wait let me see

Answer 4

Yes it is

Answer 5

\[(2 \times 10^3)(4\times 10^{-5})\]

Answer 6

Yes perfect thank you

Answer 7

I think I know what you would do can I say?

Answer 8

Do you multiply the exponents 3(-5)?

Answer 9

Okay so this case require to simplify the expression
2 * 4 = 8
And 10^3 * 10^-5 here we can simply that by adding the exponent because in multiply property we add the exponents for the expressions with the same base
So 10^3 * 10^-5 = 10^ 3+ (-5)
So 10^-2
So the final expression would be
8 x 10^-2

Answer 10

no, actually it is like \[1000/100000=1/100\]
