$(7 ^ { -10 } \times \frac{ 4 ^ { 8 } }{ 5 } +(-9) ^ { 12 } \div (-45) ^ { -3 } -6 ^ { 4 \times 5 } ) ^ { 0 }$

$Calcule \: a \: 7 \: à \: potência \: de \: -10 \: e \: obtenha \: \frac{1}{282475249}.$

$\left(\frac{1}{282475249}\times \left(\frac{4^{8}}{5}\right)+\frac{\left(-9\right)^{12}}{\left(-45\right)^{-3}}-6^{4\times 5}\right)^{0}$

$Calcule \: a \: 4 \: à \: potência de \: 8 \: e \: obtenha \: 65536.$

$\left(\frac{1}{282475249}\times \left(\frac{65536}{5}\right)+\frac{\left(-9\right)^{12}}{\left(-45\right)^{-3}}-6^{4\times 5}\right)^{0}$

$Multiplique \: \frac{1}{282475249} \: e \: \frac{65536}{5} \: para \: obter \: \frac{65536}{1412376245}.$

$\left(\frac{65536}{1412376245}+\frac{\left(-9\right)^{12}}{\left(-45\right)^{-3}}-6^{4\times 5}\right)^{0}$

$Calcule \: a \: -9 \: à \: potência \: de \: 12 \: e \: obtenha \: 282429536481.$

$\left(\frac{65536}{1412376245}+\frac{282429536481}{\left(-45\right)^{-3}}-6^{4\times 5}\right)^{0}$

$Calcule \: a \: -45 \: à \: potência \: de \: -3 \: e \: obtenha \: -\frac{1}{91125}.$

$\left(\frac{65536}{1412376245}+\frac{282429536481}{-\frac{1}{91125}}-6^{4\times 5}\right)^{0}$

$Divida \: 282429536481 \: por \: -\frac{1}{91125} \: multiplicando \: 282429536481 \: pelo \: recíproco \: de \: -\frac{1}{91125}.$

$\left(\frac{65536}{1412376245}+282429536481\left(-91125\right)-6^{4\times 5}\right)^{0}$

$Multiplique \: 282429536481 \: e \: -91125 \: para \: obter \: -25736391511831125.$

$\left(\frac{65536}{1412376245}-25736391511831125-6^{4\times 5}\right)^{0}$

$Subtraia \: 25736391511831125 \: de \: \frac{65536}{1412376245} \: para \: obter \: -\frac{36349468003329917401560089}{1412376245}.$

$\left(-\frac{36349468003329917401560089}{1412376245}-6^{4\times 5}\right)^{0}$

$Multiplique \: 4 \: e \: 5 \: para \: obter \: 20.$

$\left(-\frac{36349468003329917401560089}{1412376245}-6^{20}\right)^{0}$

$Calcule \: a \: 6 \: à \: potência \: de \: 20 \: e \: obtenha \: 3656158440062976.$

$\left(-\frac{36349468003329917401560089}{1412376245}-3656158440062976\right)^{0}$
