Question

rewrite the following expressions as formulas that can be typed into excel.
a. $=\frac{3 - 4}{8}+1$
b. $=3\cdot2^{6 - 4}$
c. $=4+\frac{5 - 7}{9\times2}+2$
d. $=\left(\frac{7}{3\cdot4^{2}}\
ight)^{2}$
b. rewrite the expression $3\cdot2^{6 - 4}$ as a formula that can be typed into excel. choose the correct answer.
○ a. $=3*2^(6 - 4)$
○ b. $=3*2^6 - 4$
○ c. $=3*(2)^6 - 4$

Explanation:

To rewrite \( 3 \cdot 2^{6 - 4} \) as an Excel formula, we need to follow Excel's syntax for exponents (using ^) and order of operations. The exponent here is \( 6 - 4 \), so we group that in parentheses after the ^ in Excel. The multiplication is represented by . So the correct Excel formula is \( = 32^(6 - 4) \), which matches option A. Option B would calculate \( 3 \cdot 2^6 - 4 \) (which is \( 3 \cdot 64 - 4 = 192 - 4 = 188 \)), while the original expression is \( 3 \cdot 2^{2}=3 \cdot 4 = 12 \), so B is incorrect. Option C incorrectly groups the 2 in parentheses (unnecessary in Excel for this and doesn't change the exponent correctly here) and still would calculate \( 3 \cdot 2^6 - 4 \) like B, so it's also incorrect.

Answer:

A. \( = 3*2^(6 - 4) \)
