Question

14,7 + 14,7 +14,7 +14,7 * 7

35,45 * 54,8 +35,45 * 35,2 + 354,5

Answer 1

  \(\text{14,7 + 14,7 +14,7 +14,7 . 7}\)

\(=14,7.\left(1+1+1+7\right)\)

\(=14,7.10\)

\(=147\)

Answer 2

     \(\text{35,45 . 54,8 +35,45 . 35,2 + 354,5}\)

\(=35,45.54,8+35,45.35,2+35,45.10\)

\(=35,45.\left(54,8+35,2+10\right)\)

\(=35,45.100\)

\(=3545\)
