Question

Feeling shameless... asking the same question 8th time..coz no one is answering... classs9 mathematics​

Answer 1

Step-by-step explanation:

Let $2^x=3^y=12^z=t$

$2=t^{1/x} \: \: \: \: \: \: 3=t^{1/y} \: \: \: \: \: \: \: 12=t^{1/z}$

See that 12 = 2*2*3

from above, see what are the values of 12,3,2.

$t^{1/z}=(t^{1/x})^2\times t^{1/y}$

$t^{1/z}=t^{2/x+1/y}$

WHEN BASES ARE SAMe, powers are equal

1/z = 2/x + 1/y.

1/z - 1/y = 2/x

Buddhi lgana nhi hai aur bolna ki feeling shameless. Ekdum ghtiya approach hai
