<PRE><B>Question 426174</B>
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)
