Well I'm not sure what your question is, but
sqrt(3) (sqrt(5) + sqrt(7))
= sqrt(3*5) + sqrt(3*7)
= sqrt(15) + sqrt(21)

?(x + 7) + 5 = x ?(x + 7) = x - 5 x + 7 = x^2 - 10x + 25 0 = x^2 - 11x + 18 0 = x^2 - 2x - 9x + 18 0 = x (x - 2) - 9 (x - 2) 0 = (x - 9) (x - 2) so x - 9 = 0 or x - 2 = 0 x = 9 or x = 2 x = 2 or 9

sqare root of 3( the sqare root of 5 + the sqare root of 7)?
=sqrt(15)+sqrt(21).
Please note sqrt(a) * sqrt(b) = sqrt(a*b)

√3 * (√5 + √7)
√15 + √21 ≈ 8.4555590411632568917673125935104
(Pardon me, 4 my finished my last calculus class in the Fall 2000 semester, so my arithmetic's a bit rusty. I do enjoy using stuff from the Character Map, thought.)

question: √3(√5+√7)
√5 = 2.23606798
√7 = 2.64575131
√5+√7 = 4.88181929
3 × 4.88181929 = 14.6454579
√14.6454579 = 3.82693845
therefore answer = 3.82693845
or 3.8 (simplified)
or 4 (to the nearest whole number)
gud luck in math clz...

√3 = 1.732
√5 = 2.236
√7 = 2.646
2.236 + 2.646 = 5.916
5.916 x 1.732
Ans. = 10.246
