Find the simplified form of the expression. give your answer in scientific notation.
(5x10^6)(3x10^5)
- 1.5x20^11
-1.5x10^12
-15x10^11
- 1.5x10^10

Scienfitic notation is
(number that is less than 10 but equal to or greater than 1) times 10^n

ok so
remeber
(ab)(ac)=(a)(b)(c)(d)
also

(5*10⁶)(3*10⁵)=
(5)(10⁶)(3)(10⁵)=
(5)(3)(10⁶)(10⁵)=
(15)(10¹¹)
remember that the first number has to be lesss than 10
15=1.5 times 10¹
(1.5)(10¹)(10¹¹)=
(1.5)(10¹²)

the answer is the 2nd option

It equals 1373.5 that’s the solution
