Question

solve all the three equation by step by step explanation.​

Answer 1

Step-by-step explanation:

i) (3+√3)(2+√2)=6+2√3+3√2+√6

ii)(√5-√2)(√5+√2)=5-√10+√10-2=3

iii)(√5+√2)^2=(√5)^2+2*√5*√2(√2)^2= 5+2√10+2=7+2√10

I hope I have answered correctly.

Answer 2

(1) (3+√3) (2+√2)

solution: 3(2+√2)+√3(2+√2). (A+B) (C+D)= A×(C+D) + B×(C+D)= AC+AD+BC+CD

6+3√2+2√3+√6

(2) (√5-√2) (√5+√2)

solution: (√5)^ - (√2)^. (A-B) (A+B) = (A)^ + (B)^

5 - 2

3

(3) (√5+√2)^

solution: (√5)^ + 2×√5×√2 + (√2)^. (A+B)^ = (A)^ + 2×a×b + (B)^

5 + 2√10 + 2

7 + 2√10
