Answer 1

Answer:4 * 10 to the power 5 + 0 + 5* 10 to the power 3 + 9 * 10 to the power 2 + 7 * 10 to the 1 + 2

Step-by-step explanation:

400000 + 00000 + 5000 + 900 + 70 +2

4 * 10 to the power 5 + 0 + 5* 10 to the power 3 + 9 * 10 to the power 2 + 7 * 10 to the 1 + 2

Answer 2

Given:

A number = 405972

To find:

The expanded form of the number using exponents.

Solution:

From the given number we can conclude that the digit 2 is in units place, 7 is in tens place, 9 is in hundreds place, 5 is in thousands place and so on.

So the number can be written as follows:

400000+ 5000+ 900+ 70+ 2

Therefore the number in expanded form using the exponents will be as follows:

$(40*10^{5}) +(5*10^{3}) +(9*10^{2}) +(7*10) +2$
