just remember that in SN, a number is written in two parts:
N x 10^p
where 1.0 <= N < 10.0
p is an integer
With that in mind, what are your choices?
3. Select all of the numbers that are correctly written in scienctific notaton
A)42 x 10^5
B) 1.1 x 10^4
C) 7.0 x 20^4
D) 6.01 x 10^-4
E) 18.0 x 10^3
4. Simply
(2.0 x 10^4)(3.0 x 10^3)
A)6.0 x 10^7
B) 6.0 x 10^12
C) 6.0 x 10^5
D) 6.0 x 10^43
5. (7.0 x 10^6)+(2.0 x 10^6)
A)9.0 x 10^4
B) 9.0 x 10^12
C)9.0 x 10^6
D) 9.0 x 10^10

I think 3 is A and E I think 4 is C and I think 5 is A
#3 A? Really? Is 42 between 1 and 10?
B,C,D are all SN.
#4 A
(2.0 x 10^4)(3.0 x 10^3)
= (2.0)(3.0) x (10^4*10^3)
= 6.0 x 10^7
#5 C
Remember the distributive rule?
ac + bc = (a+b)c
(7.0 x 10^6)+(2.0 x 10^6)
= (7.0+2.0)x10^6
= 9.0x10^6
You clearly need to study up on the rules of exponents. Scientific notation is not mysterious, but you do have to remember the basic rules of arithmetic.
