Q. Find the difference between the place values of two 7 s 7 \mathrm{~s} in 78,65,49,756 78,65,49,756 .
  1. Identify Place Value: Identify the place value of the first 77, which is in the ten millions place.\newlineSo, the place value of the first 77 is 7×10,000,000=70,000,0007 \times 10,000,000 = 70,000,000.
  2. Calculate Second Place Value: Identify the place value of the second 77, which is in the thousands place.\newlineSo, the place value of the second 77 is 7×1,000=7,0007 \times 1,000 = 7,000.
  3. Calculate Difference: Calculate the difference between the two place values.\newlineDifference = 70,000,000−7,000=69,993,00070,000,000 - 7,000 = 69,993,000.
