Answer ASAP - NO LINKS- 50 POINTS Simplify the mathematical expressions to determine the product or quotient in scientific notation. Round so the first factor goes to the tenths place.

3.1x10^6

3.6x10^-1

4.2x10^-1

5.3x10^6

Expressions match with these

(3.8x10^3)x(9.4x10^-5)

(4.2x10^7)x(7.4x10^-2)

(8.6x10^-6)x(7.1x10^-9) / (4.1x10^-2)x(2.8x10^-7)

(6.9x10^-4)x(7.7x10^-6) / (2.7x10^-2)x(4.7x10^-7)
