Answer
$(2$$\times$$10^{5}$$)+$$(9$$\times$$10^{4}$$)+$$(4$$\times$$10^{3}$$)$$+(8$$\times$$10^{2}$$)$$+(6$$\times$$10^{1}$$)$$+(3$$\times$$10^{0}$$)$
Work Step by Step
First, write 294,863 out as an addition problem using each digits place value
For example, 200000+90000+4000+800+60+3
Now, use the powers of 10 on the expanded form above
$(2$$\times$$10^{5}$$)+$$(9$$\times$$10^{4}$$)+$$(4$$\times$$10^{3}$$)$$+(8$$\times$$10^{2}$$)$$+(6$$\times$$10^{1}$$)$$+(3$$\times$$10^{0}$$)$
