Question

ii) If x² + y² = 6xy then show that 2log(x+ y) = 3 log 2 +log x+log y​

Answer 1

Answer:

to prove

xsquare+ysquare=6xy

Step-by-step explanation:

2log(x+y)=3log2+logx+logy

log(x+y)the whole square=log 2 whole cube+logx+logy

log(x square+y square+2xy)=log8+logxy

log(x square+y square+2xy)=log8xy

taking antilog on both sides

xsquare+ysquare+2xy=8xy

xsquare+ysquare=8xy-2xy

xsquare+ysquare=6xy
