Answer 4

\(\left(2^3.9^4+9^3.45\right):\left(9^2.10-9^2\right)\)

\(=\left(2^3.9^4+9^3.9.5\right):\left(9^2.9\right)\)

\(=[9^4\left(2^3+5\right)]:9^3\)

\(=9^4.13:9^3\)

\(=9.13\)

\(=117\)

Answer 5

\(\left(2^3.9^4+9^3.45\right):\left(9^2.10-9^2\right)\)

\(=\left(2^3.9^4+9^4.5\right):\left[9^2\left(10-1\right)\right]\)

\(=9^4.13:9^3\)

=9.13

=117
