Question

simplify the following.......
i) (4√3-2√2)
ii) (2+√3)(3+√5))

Answer 1

i)(4√3-2√2)
=4.09977611
ii)(2+√3)(3+√5)
=19.5412717

Answer 2

(1)

√3 = 1.73
√2 = 1.41

Therefore,

4√3 - 2√2
= 4(1.73) - 2(1.41)
= 6.92 - 2.82
= 4.10

(2)

√3 = 1.73
√5 = 2.23

Therefore,

(2+√3)(3+√5)
= (2 + 1.73)(3 + 2.23)
= 3.73 × 5.23
= 19.54

That's your answer.

Hope it'll help.. ;-)
