Answer:

  • S = 55√3

Step-by-step explanation:

S=

  • √3+2√3+3√3+...10√3 =
  • √3( 1 + 2 + 3+...+ 10) =
  • √3(1/2)(10)(10 + 1) =
  • √3(55) =
  • 55√3

S = 55√3

Answer:

s=✓3(1+2+3+...10)

s=✓3[10/2×(10+1)]

here, applying sum of 1st n natural number is n/2×(n+1)

so, s=✓3×5×11

hence, s=55✓3.
