Question

\(\left(20.2^4-12.2^3-48.2^2\right)^2:\left(-8\right)^3\)

Answer 1

\(\left(20.2^4-12.2^3-48.2^2\right)^2:\left(-8^3\right)\)

\(=\left(20.16-12.8-48.4\right)^2:\left(-512\right)\)

\(=\left(320-96-192\right)^2:\left(-512\right)\)

\(=\left(224-192\right)^2:\left(-512\right)\)

\(=32^2:\left(-512\right)\)

\(=\left(32^2:-512\right)\)

\(=\left(1024:-512\right)\)

\(=-2\)
