Zachary adds 26.45 g to 2.55 g. How many significant figures should his answer have?

<em><u>26.45 + 2.55 = 29 . . . but with correct sig figs . . . the answer is . . . 29.00 . . . i.e. [4] sig figs</u></em>

. . . why? . . . because even though 26.45 has [4] sig figs & 2.55 has [3] sig figs, the number of sig figs to the right of the decimal are the critical sig figs . . . and there are [2] sig figs to the right of the decimal, so the answer/result can also beas precise as having [2] sig figs to the right of the decimal as well.

Simplify 4x(2x3-7x2+x)

Gelneren [198K]

To simplify this all you need to do is distribute the 4x across each term in the parenthesis
$4x(2x^3 - 7x^2 + x) \\ (4x)(2x^3) - (4x)(7x^2) + (4x)(x) \\ 8x^4 - 28x^3 + 4x^2$
