Question

(5 + √7) (2 + √5) Answer plz​

Answer 1

Answer:

(5+√7) (2+√5)

10+5√5+2√7+√35

Answer 2

(5+√7) (2+√5)

So lets divide this in two parts.

Part 1 - (5+√7)

Part 2 - (2+√5)

PART 1:

Square root of 7 = Lets take it as 2.6

So:

(5+2.6)

Do you agree?

Part 2

Square root of 5 = Lets take it as 2.2

So:

(2+2.2)

Hopefully you agree.

Answer:

Now we are going to multiply both expressions.

(5+2.6) * (2+2.2)

But first we are going to further simplify them.

7.6 * 4.2

Agreed?

Answer - 31.92
