Answer:

243.92 = 2.4392 × 1002


Negative Exponents

1.82371 × 101= 1.82371 × 10= 18.2371(move the point 1 place right)
1.82371 × 10-1= 1.82371 × .1= .182371(move the point 1 place left)
1.82371 × 102= 1.82371 × 100= 182.371(move the point 2 places right)
1.82371 × 10-2= 1.82371 × .01= .0182371(move the point 2 places left)

The exponent shows by what power of 10 to multiply the mantissa, or (the same thing) how far to float the decimal point.

10+n   means move the decimal point n places right.

10-n   means move the decimal point n places left.
