Question

Calculați: [( -3 )⁷]² : (-3)¹¹ + (-2) • (-2)³ : (-2)⁴​

Answer 1

$[( -3 )^7]^2 : (-3)^{11} + (-2) \cdot (-2)^3 : (-2)^4 =$

$\frac{\left[\left(-3\right)^7\right]^2}{\left(-3\right)^{11}}+\left(-2\right)\cdot \frac{\left(-2\right)^3}{\left(-2\right)^4}=-26\\=\frac{\left(\left(-3\right)^7\right)^2}{\left(-3\right)^{11}}-2\cdot \frac{\left(-2\right)^3}{\left(-2\right)^4}\\=-27-\left(-1\right)\\ =-27+1 = 26$
