p = log10(20) , q = log10(25)
2log10(x+1) = 2p-q
2p = 2log10(20) = log10(20²)
2p = log10(400)
2p-q = log10(400) - log10(25)
= log10(400/25) = log10(16)
2log10(x+1) = log10(4²) = 2log10(4)
x+1=4
Hence , x=3
2log10(x+1) = 2p-q
2p = 2log10(20) = log10(20²)
2p = log10(400)
2p-q = log10(400) - log10(25)
= log10(400/25) = log10(16)
2log10(x+1) = log10(4²) = 2log10(4)
x+1=4
Hence , x=3
