Para encontrar o valor da expressão numérica, devemos começar as operações dos parênteses mais internos:
![25-\left[16:(11-\sqrt{49})-(2^{3}+\sqrt{25})^{2} \right]\\\\ =25-\left[16:(11-7)-(8+5)^{2} \right ]\\\\ =25-\left[16:4-13^{2} \right ]\\\\ =25-\left[16:4-169 \right ]\\\\ =25-\left[4-169 \right ]\\\\ =25-\left[-165 \right ]\\\\ =25+165\\\\ =190](https://tex.z-dn.net/?f=25-%5Cleft%5B16%3A%2811-%5Csqrt%7B49%7D%29-%282%5E%7B3%7D%2B%5Csqrt%7B25%7D%29%5E%7B2%7D+%5Cright%5D%5C%5C%5C%5C+%3D25-%5Cleft%5B16%3A%2811-7%29-%288%2B5%29%5E%7B2%7D+%5Cright+%5D%5C%5C%5C%5C+%3D25-%5Cleft%5B16%3A4-13%5E%7B2%7D+%5Cright+%5D%5C%5C%5C%5C+%3D25-%5Cleft%5B16%3A4-169+%5Cright+%5D%5C%5C%5C%5C+%3D25-%5Cleft%5B4-169+%5Cright+%5D%5C%5C%5C%5C+%3D25-%5Cleft%5B-165+%5Cright+%5D%5C%5C%5C%5C+%3D25%2B165%5C%5C%5C%5C+%3D190 "25-\left[16:(11-\sqrt{49})-(2^{3}+\sqrt{25})^{2} \right]\\\\ =25-\left[16:(11-7)-(8+5)^{2} \right ]\\\\ =25-\left[16:4-13^{2} \right ]\\\\ =25-\left[16:4-169 \right ]\\\\ =25-\left[4-169 \right ]\\\\ =25-\left[-165 \right ]\\\\ =25+165\\\\ =190")
