Question

(-48).54 +(-48) .46+480

900:(50+(7² -8.3).2)+2022⁰

Answer 1

\(\left(-48\right).54+\left(-48\right).46+480\)

\(=\left(-48\right).\left(54+46\right)+480\)

\(=\left(-48\right).100+480\)

\(=-4800+480\)

\(=-4320\)

_________

\(900:\left[50+\left(7^2-8.3\right).2\right]+2022^0\)

\(=900:\left[50+\left(49-24\right).2\right]+1\)

\(=900:\left[50+25.2\right]+1\)

\(=900:\left[50+50\right]+1\)

\(=900:100+1\)

\(=9+1=10\)

Answer 2

= (-48) . (54+46) + 480                            = 

= (-48) . 100 + 480

= (-4800) + 480

= - 4320
