Answer:

#100,000#

Explanation:

Look at the ten thousand's part of 98,464.

So the cut off point is#" "9 color(magenta)(|)8464 #
#" "color(white)(.)color(red)(uarr)#
#" "color(red)("Cut off point")#

The digit to the right of the cut off point is greater than 5 so we round up the #color(red)(9)# by 1 turning it into #color(blue)(10)#. The digits to the right of the cut off point are all changed to 0 giving:

#" ten thousands"#
#" " darr#
#color(white)(10.)color(red)(9)8,464 larr" original number"#
#color(white)(..)color(blue)(10)0,000 larr" rounded number"#
