Question

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?

Answer 1

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.

$(4.296 * 10^{11}) * (1.8614 * 10^{-14})= \\ \\ 4.296*1.8614*10^{11+(-14)}=\\\\7.99657*10^{-3}= \\ \\ \cfrac{7.99657}{1000}=\\\\0.00799657$
