I believe it's n=-4? It's a negative because the decimal moves to the right 4 times to get 70,000
70000 = 7 ⋅ 1 0 4 840000000 = 8 , 4 ⋅ 1 0 8 0 , 004 = 4 ⋅ 1 0 − 3 0 , 000000123 = 1 , 23 ⋅ 1 0 − 7
The number 70,000 can be expressed in scientific notation as 7.0 × 1 0 4 . This means the value of n is 4, as we move the decimal point 4 places to the left. Therefore, n = 4 .
