- To express a number in standard form, we write it as a decimal number between 1.0 and 10.0 multiplied by a power of 10.
- For (i) 59,853: Move the decimal point from the end to after the first digit. The decimal point moves 4 places to the left. So, 59,853 = 5.9853 × 10^4.
- For (ii) 65,950: Move the decimal point from the end to after the first digit. The decimal point moves 4 places to the left. So, 65,950 = 6.5950 × 10^4.
- For (iii) 34,30,000: Move the decimal point from the end to after the first digit. The decimal point moves 6 places to the left. So, 34,30,000 = 3.43 × 10^6.
- For (iv) 70,04,00,00,000: Move the decimal point from the end to after the first digit. The decimal point moves 10 places to the left. So, 70,04,00,00,000 = 7.004 × 10^10.
