Question

Let p= log 10x, q= log10, y and r= log10z.

Write the expression log10 $(\frac{x}{y^{2} \sqrt{z} }$) in terms of p, q and r.

Answer 1

when the is x−y

⟾ =5 ht

⟾ Dist =S×T

⟾ 100=(x−y)5

⟾ x−y=20⟶(I)

when THE is x+y

⟾ Dit=10

⟾ t=1 ht

⟾ 100=(x+y)1

⟾ x+y=100⟶(II)

⟾ x−y=20

⟾ x+y=100

​⟾ 2x=120

⟾ x=60
