Question

calculați (-2)²¹:4¹⁰+3¹⁰:(-9)³-(-5)¹¹:25⁵​

Answer 1

Explicație pas cu pas:

$( - 2) ^{21} \div (( - 2)^{2})^{10} + ( - 3)^{10} \div (( - 3)^{3})^{3} - ( - 5)^{11} \div (( - 5)^{2})^{5}$

$(- 2)^{21} \div ({ - 2})^{20} + ({ -3})^{10} \div ( - 3) {}^{6} - ( - 5) {}^{11} \div ( - 5) {}^{10}$

$- 2 + ( - 3) {}^{4} - ( - 5)$

$- 2 + 81 + 5$

$- 2 + 86$

$84$
