1. uSE LOGORITHMS TO SOLVE FOR GIVEN EQUATION. rOUND THE ANSWER TO FOUR DECIMALS. 6.9(10^X)=4.
2. uSE LOGORITHMS TO SOLVE FOR GIVEN EQUATION. rOUND THE ANSWER TO FOUR DECIMALS. 6(1.05^2X+1)=7
..
1.6.9(10^X)=4
10^x=4/6.9
xlog10=log4-log6.9
x=(log4-log6.9)/log10
x=-0.2368 (ans)
..
2.6(1.05^2X+1)=7
(6)1.05^2x+6=7
(6)1.05^2x=1
1.05^2x=1/6
2xlog1.05=log1-log6
x=(log1-log6)/2log1.05=-18.3619 (ans)
