Question

Divide 5 root 45 by root 75 upon root 5

Answer 1

5√45 ÷ √75/√5
⇒ 5 √45  × √5 / √75
 5 √45 × √5 = 5 √225 = 5 × 15 = 75 
⇒ 75 / √75 
⇒ √75 × √75 divided by √75 
⇒ √75 

so, the answer is √75

Answer 2

The question given to us is (5√45) ÷ (√75)/√5

5√45 can be written as √(3 x 3 x 5 x 5 x 5)
√75 can be written as √(3 x 5 x 5)

(5√45) ÷ (√75)/√5 = √(3 x 3 x 5 x 5 x 5) x √5/ √(3 x 5 x 5)

Simplifying this will give us the value as √75 or 5√3 (answer)
