Question

PLS va rog sa ma ajutați!

Answer 1

Răspuns:

$=\Big(\frac{641}{90} \Big)^{6}$

Explicație pas cu pas:

$7\frac{11}{90} =\frac{7 \cdot 90 + 11}{90} =\frac{641}{90}$

$\Big[\Big(7\frac{11}{90} \Big)^{3} \Big]^{2} =\Big[\Big(\frac{641}{90} \Big)^{3} \Big]^{2} =\Big(\frac{641}{90} \Big)^{3 \: \cdot \: 2} =\boxed{\Big(\frac{641}{90 }\Big)^{6}}$

Answer 2

$\it \Big[\Big(7\dfrac{11}{90}\Big)^3\Big]^2=\Big(\dfrac{641}{90}\Big)^6=\dfrac{641^6}{90^6}$
