Multiplication Patterns

Use mental math to complete the pattern.

  • Question 1 (request help)

    8 x 3 = 24
    (8 x 3) x 101 = 240
    (8 x 3) x 102 = 2,400
    (8 x 3) x 103 =24,000
  • Question 2 (request help)
  • \(5\times6 = \)   
    \((5\times6)\times10^1 =\)   
    \((5\times6)\times10^2 =\)   
    \((5\times6)\times10^3 =\)   
  • Question 3 (request help)
  • \(3\times\)   \(= 27\)
    \((3\times9)\times10^1 =\)   
    \((3\times9)\times10^2 =\)   
    \((3\times9)\times10^3 =\)   
  • Question 4 (request help)

     \(\begin{align}
    ? \times4 &= 28\\
    (7 \times 4) \times? &= 280\\
    (7 \times4) \times? &= 2,800\\
    (7 \times4) \times? &=28,000\\
    \end{align}\)
  • Type below:
  • Question 5 (request help)
  • \(6\times8 =\)   
    \((6\times8)\times10^2 =\)   
    \((6\times8)\times10^3 =\)   
    \((6\times8)\times10^4 =\)   
  • Question 6 (request help)
  • \(16 = 4 \times\)   
    \((4\times4)\times10^2 =\)   
    \((4\times4)\times10^3 =\)   
    \((4\times4)\times10^4 =\)   

Use mental math and a pattern to find the product.
