Simplify 7 square root 2535

Answers

Answer:

The value of 7 square root 2535 is 352.443 or 91√(15).

Step-by-step explanation:

Consider the provided expression.

7√(2535)

The value of √(2535) is 50.349 approximately or 13√15

Now substitute the value of √(2535) in above expression.

7* 50.349 or 7* 13√(15)

352.443 or 91√(15)

Hence, the value of 7 square root 2535 is 352.443 or 91√(15).
 7*sqrt(3*5*13^2) = 91*sqrt(15) = 91*3.872983346 = 352.4414845
