lg x = p, lg y = q
lg √(10x³y)
= lg (10x³y)¹/²
= ½lg (10x³y)
= ½ (lg 10 + lg x³ + lg y)
= ½ (1 + 3lg x + q)
= ½ (1 + 3p + q)
= ½ + 3/2 p + ½ q
lg √(10x³y)
= lg (10x³y)¹/²
= ½lg (10x³y)
= ½ (lg 10 + lg x³ + lg y)
= ½ (1 + 3lg x + q)
= ½ (1 + 3p + q)
= ½ + 3/2 p + ½ q
thank you !!!

lg (10x^3 y)^(1/2)
= 1/2 (lg 10 + lg x^3 + lg y)
= 1/2 (1 + 3 lg x + lg y)
= 1/2 (1 + 3p + q)
= 1/2 (lg 10 + lg x^3 + lg y)
= 1/2 (1 + 3 lg x + lg y)
= 1/2 (1 + 3p + q)
