Question

Aratati ca numarul a x b este patrat perfect,stiind ca a=4950radical2 si b=radical968

Answer 1

Răspuns:

$a \times b = p.p$

$a = 4950 \sqrt{2}$

$b = \sqrt{968}$

$4950 \sqrt{2} \times \sqrt{968} = p.p$

$4950 \sqrt{1936} = p.p$

$4950 \times 44 = p.p$

$217.800 = p.p$

Answer 2

Răspuns:

$a = 4950 \sqrt{2 \\ } \: \: b = \sqrt{968}$

$a \times b = 4950 \sqrt{2 \times 968 } = 4950 \times \sqrt{1936} = 4950 \times 44 = 217800$
