Question

12×125×54

b.64×125×54

c.36×[143+57)+64+(143+57)

d.78×31+78×24+70×22×22×72

e.64×14+9×59

 

 

 

Answer 1

\(a.12\times125\times54\)

\(=1500\times54\)

\(=81000\)

\(b.64\times125\times54\)

\(=8000\times54\)

\(=432000\)

\(c.36\times\left[143+57\right]+64+\left(143+57\right)\)

\(=36\times200+64+200\)

\(=7200+64+200\)

\(=7264+200\)

\(=7464\)
