Yep!

7√7 - 2√7

= 5√7

Good luck!

Sqrt 343 = Sqrt7 *Sqrt49 = 7Sqrt7

Sqrt28 = Sqrt7* Sqrt4 = 2 Sqrt7

7Sqrt7 - 2Sqrt7 = 5Sqrt7

sqrt 343 - sqrt 28

= sqrt (7^3) - sqrt (4)(7)

= 7sqrt7 - 2sqrt7

=5 sqrt7

sqrt(343) - sqrt(28)

= sqrt(49*7) - sqrt(4*7)

= sqrt(7*7*7) - sqrt(2*2*7)

=7sqrt(7) - 2sqrt(7)

= 5sqrt(7)

sqrt(343) - sqrt(28)

sqrt(7)sqrt(49) - sqrt(4)sqrt(7)

7sqrt(7) - 2sqrt(7)

5sqrt(7)

sq rt 343- sq rt 28

sq rt 49* sq rt 7- sq rt 4*sq rt 7

7 sq rt 7-2 sq rt 7

5 sq rt 7
