Question

Determine o valor numérico de a²b² sabendo que a=2√5 e b=3√3

Answer 1

Resposta:

a²*b² =  

(2√5)² * (3√3)² =  

4*5 * 9*3 =  

20 * 27 = 540

Answer 2

Resposta:

$a = 2\sqrt{5} \\b = 3\sqrt{3} \\\\a^{2} = (2\sqrt{5} )^{2} = 4 * 5 = 20\\b^{2} = (3\sqrt{3} )^{2} = 9 * 3 = 27\\\\A^{2} B^{2} = 20 * 27 = 540$
