Bethany wants to estimate the value of (4.296 x 10^11) x (1.8614 x 10^-14). which statement about the estimate is true?
a. the value will be greater than 1 because 4.296 x 10^11 is a very large number and multiplication always increases the size of a number.
b. the value will be greater than 1 because 4 x 2 = 8 and 8 is larger than 1.
c. the value will be less than 1 because (4.296 x 10^11) x (1.8614 x 10^-14) will be a negative number. all negative numbers are less than one.
d. the number will be less than 1 because when adding the exponents,
11 + (-14) = 3, and a number in scientific notation with a negative exponent is less than 1.
