Answer (1 of 6) It is given that (x1)^3 =8 and we have to find the value of (x1)^2 So, (x1)^3 = 8 => (x1)^3 = 2^3 as 8 = 2^3 the exponents being equal on both sides of equation cancel out each other, so x1 = 2;Answer (1 of 8) Given 2^x=3^y=6^z Lets assume that each and every term is equal to k Which implies 2^x=k Now by applying logarithm on both sides we get x=log k to base 2 and 1/x= log 2 to base k And 3^y=k Again by applying logarithm on both sides we get y=log k to base 3 and 1/y=log 3After a little manipulation, we reach x=3\sqrt {2x^2} A reasonable thing to do is to square both sides We reach x^2=1x^2 It is easy to see that this equation has no real solution so there After a little manipulation, we reach x = 3 2x2 A reasonable thing to do is to square both sides
