Question

rewrite the following expressions as a formula that can be typed into excel.
a. $=\frac{3 - 4}{6}+8$
b. $=2\cdot4^{6}-1$
c. $=2 + \frac{3 - 7}{9\times3}+5$
d. $=\left(\frac{7}{4\cdot3^{2}}\
ight)^{2}$

a. choose the correct answer below

a. $=(3 - 4)/6 + 8$
b. $=((3 - 4)/(6 + 8))$
c. $=3 - 4/6 + 8$
d. $=(3 - 4/6)+8$

Explanation:

The original expression is \(\frac{3 - 4}{6}+8\). In Excel, division is represented by \(/\) and we need to group the numerator \(3 - 4\) using parentheses to ensure the subtraction is done first before division. Option A correctly groups \(3 - 4\) as \((3 - 4)\), then divides by 6 (\((3 - 4)/6\)) and adds 8. Option B incorrectly groups the denominator as \(6 + 8\), Option C and D do not correctly group the numerator for the division (they would perform \(4/6\) first instead of \(3 - 4\) first).

Answer:

A. \(=(3 - 4)/6 + 8\)
