Answer (2)

7.0 ⋅ 1 0 4 + 6.0 ⋅ 1 0 3 = 1 0 3 ⋅ ( 7.0 ⋅ 10 + 6.0 ) = ( 70.0 + 6.0 ) ⋅ 1 0 3 = 76 ⋅ 1 0 3 A n s w er : D ) 76 ⋅ 1 0 3

The expression 7.0 × 1 0 4 + 6.0 × 1 0 3 evaluates to 76 × 1 0 3 . The correct answer is option D. By rewriting both terms with the same exponent, we simplified the addition easily.
