Answer:

it means replace x with 27

Explanation:


\sqrt[3]{27 + 98} + 5 = \sqrt[3]{125} + 5 = 5 + 5 = 10

Answer:

10

Explanation:

f(27) means to replace the x, not f(x). This means the equation would be
f(27)=\sqrt[3]{27+98}+5. First, take the cube root of 27 + 98 (125), which equals 5. Then add this to the 5 on the outside of the cube root to get 10.
