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

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
