Answer:

Step-by-step explanation:

When we subtracting variables with exponent, both should have same exponents

6.28 * 10⁶ -  1.256*10⁵ = 62.8 *10⁵ - 1.256*10⁵

                                    = (62.8 - 1.256) *10⁵

                                   = 61.544 *10⁵

                                  = 6.1544 *10⁶
