Answer» Given $x = l o g_{10} 12$ , $y = l o g_{4} 2 \times l o g_{10} 9$ and $z = l o g_{10} 0.4$ , find : (i) $x - y - z$ (ii) $13^{x - y - z}$

Given x=log10 12, y=log4 2×log10 9 and z=log10 0.4, find : (i) x−y−z (ii) 13x−y−z

Answer»

Given $x = l o g_{10} 12$ , $y = l o g_{4} 2 \times l o g_{10} 9$ and $z = l o g_{10} 0.4$ , find :

(i) $x - y - z$

(ii) $13^{x - y - z}$
