Answer 1

you got the 1st part right

the numbers multiply ... the exponents add

Answer 2

so its 1.632 times 10^7 ?

Answer 3

I suggest this method
(5.1 times 10^3) times (3.2 times 10^3)
= (5.1)(10^3)(3.2)(10^3)
= (5.1)(3.2)(10^3)(10^3)
= (16.32)(10^6)
= (1.632)(10^1)(10^6) = 1.632 x 10^7

seems rather long-winded, but it is easy to understand

Answer 4

so you multiply the decimals add the exponents move the decimal point? thats kind of like gibberish to me lol i suck at math
