Question

X*y^0*z^-1=??? please solve this question

Answer 1

Answer:

The answer is $\frac{X}{Z}$  

Step-by-step explanation:

Given problem  $X$ × $Y ^{0}$ × $Z^{-1}$    

⇒   $X$ × $1$ × $Z^{-1}$    [ ∵  Y⁰=0 ]    

⇒   $X$ × 1 ×  $\frac{1}{Z}$       [ ∵ Z⁻1 = $\frac{1}{Z}$  ]  

⇒      $\frac{X}{Z}$    

Therefore, $X$ × $Y ^{0}$ × $Z^{-1}$ =   $\frac{X}{Z}$
