Answer 2

Hello !!

It not is possible simplify because your simplify for is 4√5 + 5√2.

But, we only can put the result in decimal form also !

FIND THE SQUARE ROOT OF 5.

√N ≅ (N + B)/(2√B)

√5 ≅ (5 + 4)/(2√4)

√5 ≅ 9/(2 × 2)

√5 ≅ 9/4

√5 ≅ 2.25

FIND THE SQUARE ROOT OF 2.

√N ≅ (N + B)/(2√B)

√2 ≅ (2 + 1)/(2√1)

√2 ≅ 3/(2 × 1)

√2 ≅ 3/2

√2 ≅ 1.5

Now, we find 4 × 2.25 + 5 × 1.5

4 × 2.25 + 5 × 1.5

= 9 + 7.5

= 16.5

Therefore, your simplify form is 4√5 + 5√2 and your decimal form is approximately 16.5

I hope I have collaborated !
