Answer:
Step-by-step explanation:
√63 - 5 √28 + 11 √7
= √9*7 - 5√4*7 + 11√7
= As √9 = 3 and √4 = 2 to make is simpler we can write it as 3 and 2 respectively.
√3*7 - 5√2*7 + 11√7
As 7 is common in all the equations and if we take the 7 outside we will have this:
3√7 - 5*2√7 + 11√7
= 3 √7 - 10√7 + 11√7
Now, we can add all the numbers except the 7
3-10 +11 (√7)
= 3 √7
I hope this helps you understand
