Answer is 95+10 √5


​

Answer 1

Answer:

95+20√15

Step-by-step explanation:

(a+b)^2=a

$(x + y)^{2} = x { }^{2} + y {}^{2} + 2xy$

therefore

5^2×3+2^2×5+2×5√3×2√5

=75+20+5×2×2×√5√3

=95+20√15

hope this helps

thank u

Answer 2

Step-by-step explanation:

we will use the formula (a+b)² to simplify this question

1. (5√3+2√5)²

opening the bracket we will transfer it in the form...a²+b²+2ab

here a=5√3 and b= 2√3

(5√3)²+(2√5)²+2*5√3*2√5

now we will open the brackets

25*3+4*5+2*5*2√5*3

simplifying the rest

75+20+20√15

95+20√15 .... ans

thank u and comment for any doubt
