Question

19. Simplified value of (125)^2/3 x √25 x 3√5^3 x 5^1/2 is
(a) 5
(b) 1/5
(c)1
(d) none of these​

Answer 1

Answer:

(d) none of the above

Step-by-step explanation:

(125)^⅔ = (5³)^⅔ = 5^(⁶/³) = 5²

√25 = 5 (taking positive value only)

3√5³ = (5)^(³/³) = 5

5^(¹/²) = √5

putting these value

we get, 5² × 5 × 5 × √5 = 625×√5
