Please Help me with this

A) .071

B).884

Step-by-step explanation:

A) 7.1 x 10/\-2

This is scientific notation, since this is to the -2 power all you have to do is move the decimal point 2 places to the left, thus making the number smaller -> 7.1->.71->.071

B) (6.8 x 10/\2) x (1.3 x 10/\-3)

Again, Scientific notation

6.8->68->680

1.3->.13->.013->.0013

then multiply

680 x .0013 = .884

for b its (t) and c its (d)
