EXPONENTIALS 2


If 502w (40w) = 10000008 ; Find w.

Solution

502w (40w) = 10000008

(502)w (40w) = (106 ) 8

(2500)w (40w) = 106x8

(2500 x 40)w = 1048

(100000)w = 1048

(105)w = 1048

105w = 1048   (Bases are alike, so they cancel out)

5w = 48

5w = 4814.4
5        5

w = 9.6 answer

TRY THIS…………………………….
