Formulas - Math

We can write mathematical expressions in formulas. The expression \[\frac{4}{5}\cdot 10 + 13\] can be written as

=(4/5)*10+13

When writing fractions that have multiple terms, group terms with parentheses. The expression \[\frac{5-1}{2+3}\] is written in a formula as:

=(5-1)/(2+3)

Exponents use the symbol ^, i.e., \(2^{5}\) is =2^5

1. In A1, write the formula for \(1+2+3\)
2. In B1, write the formula for \(\frac{2^3}{4+1}\)
3. In C1, write the formula for \(\left(\frac{1+7}{4^2}\right)^3\)
