You dont know the values of x or y but you are given log10x8

You don\'t know the values of x or y, but you are given

log10x=8.7, log10y=5.

Calculate numerical values for each of the following

Solution

given log10x=8.7, log10y=5.

log10x = 8.7

log10 + logx = 8.7

1 + logx = 8.7

logx = 8.7 -1

logx = 7.7

x = 10^7.7

x = 10^7.7

log10y=5

10y = 10^5

y = 10^4
