Question

Answer 1

i)
    \(-8-45:\left(-3\right)^2+2024^0\cdot\left(-1\right)\)
\(=-8-45:9+1\cdot\left(-1\right)\)
\(=-8-5+\left(-1\right)\)
\(=-14\)

j)
    \(\left[27\cdot\left(-67\right)+33\cdot\left(-27\right)\right]:\left(-30\right)\)
\(=\left[\left(-27\right)\cdot67+33\cdot\left(-27\right)\right]:\left(-30\right)\)
\(=\left[\left(-27\right)\left(67+33\right)\right]:\left(-30\right)\)
\(=\left[\left(-27\right)\cdot100\right]:\left(-30\right)\)
\(=\left(-2700\right):\left(-30\right)\)
\(=90\)

k)
    \(11^{25}:11^{23}-3^5:\left(1^{10}+2^3\right)-60\)
\(=11^{25}:11^{23}-3^5:9-60\)
\(=11^{25}:11^{23}-3^5:3^2-60\)
\(=11^2-3^3-60\)
\(=121-27-60\)
\(=34\)

l)
    \(29-\left[16+3\cdot\left(51-49\right)\right]\)
\(=29-\left[16+3\cdot2\right]\)
\(=29-25\)
\(=4\)
