Express your answer in scientific notation. 4.9\cdot 10^{5} - 5.8 \cdot 10^{4} =4.9⋅10 5 −5.8⋅10 4 =4, point, 9, dot, 10, start
tatyana61 [14]

Answer:

4.32*10^{5}

Step-by-step explanation:

Given the expression 4.9*10^{5}-5.8*10^{4}, to solve the expression, we need to write both scientific notation to the same power of 10.

5.8*10^{4} is \ expressed\  as \ 0.58*10^{5}

The expression above becomes 4.9*10^{5}-0.58*10^{5}. On taking the difference;

4.9*10^{5}-0.58*10^{5}\\= (4.9-0.58)*10^{5} \\= 4.32*10^{5}

The final expression gives the right answer
