Question

Para a^4=5 e b^5=3 calcule o valor de a^2•a^3•b^3•b^4•a^3•b^3

Answer 1

Resposta:

225

Explicação passo-a-passo:

$a^{4}=5\\b^{5}=3\\\\ a^{2}.a^{3}.b^{3}.b^{4}.a^{3}.b^{3}=\\a^{2}.a^{3}.a^{3}.b^{3}.b^{4}.b^{3}=\\a^{2+3+3}.b^{3+4+3}=\\a^{8}.b^{10}=\\(a^{4})^{2}.(b^{5})^{2}=\\5^{2}.3^{2}=\\25.9=225$
