Solution

The correct option is A
True

Given: $a^{x} = b, b^{y} = c a n d c^{z} = a$

$a^{x} = b$

Raising both sides to the power $y z$ we get

$a^{x y z} = b^{y z}$

= $(b^{y})^{z}$

= $c^{z}$

= $a$

Since` $a^{x y z} = a$ , we get $x y z = 1$

State true or false:

a^{x} = b, b^{y} = c

c^{z} = a

x y z = 1

.

a^{x} = b, b^{y} = c, c^{z} = a

x y z = ?

a^{x} = b, b^{y} = c, c^{z} = a

x y z = 1

a^{x} = \sqrt{b}, b^{y} = \sqrt[3]{c}

c^{z} = \sqrt{a}

then the value of

x y z

a^{x} = b, b^{y} = c, c^{z} = a,

, then the value of

x y z
