1) Lgx = - 2 (2) lgx = 21ga LGB (3) LNX = 0.7 (4) LNX = 1-ln4 (process)


1)10^lgX=10^(-2)---->X=0.01
2)lgx=lg(a^21/b)--->10^lgX=10^lg(a^21/b)--->X=a^21/b
3)e^lnX=e^0.7---->X=e^0.7
4)lnX=lne-ln4=ln(e/4)--->e^lnX=e^n(e/4)--->X=e/4



lg10/2*lg(10*2)=(1-lg^2)(1+lg^2)
Explain why LG10 / 2 * LG (10 * 2) can be changed to (1-lg ^ 2) (1 + LG ^ 2)


lg10/2=lg10-lg2=1-lg2
lg(10*2）=lg10+lg2=1+lg2



lg10^2=?


Original formula = 2lg10
=2×1
=2
