WebThe mantissa is .021 and has 3 digits because 10.5 has 3 sig figs). NOTE: It is the number of digits , not the number of sig figs in the mantissa 7. For exponents, the number of sig figs is the same as the number of digits in the mantissa. For example 101.23 = 17 or 1.7 x 101. This has 2 sig figs because there are 2 digits in the mantissa (.23). 8. WebThe decimal should be placed between the 8 and 7 to be in proper scientific notation. That also changes the power, or exponent, of 10. To put 87.2 x 10 2 in proper format, move the decimal: 8.72 x 103. The exponent, or power of 10, increased by 1 because we moved the decimal place one space to the left.
