Multiply 104 by 102

  1. 108
  2. 102
  3. 106
  4. 10-2
  5. 103

C: When multiplying terms with the same base, the exponents should be added. Thus, 104 . 102=106.

 Find 8.23 x 109

  1. 0.00000000823
  2. 0.000000823
  3. 8.23
  4. 8230000000
  5. 823000000000

 D: The decimal will be moved to the right 9 places. Thus 7 zeros will be added to the right of 823, giving 8,230,000,000.

83,000 equals:

  1. 83.0 x 104
  2. 8.3 x 104
  3. 8.3 x 103
  4. 83.0 x 105
  5. 83.0 x 102

B: Moving the decimal to the right of the digit, 8, gives the equivalent expression, 8.3x104, since there are 4 digits to the right of the 8.
