Question 1121396

I am having a hard time understanding this problem. I am confused at what symbols they are referring to. I'm thinking it has to do with making a different expression using square roots, cubes, etc. Could you please help???
Here is the question:
Without grouping symbols, the expression 2 x 3^3+4 has a value of 58. Insert grouping symbols in the expression 2 x 3^3+4 to produce the indicated values.
a) 62
b) 220
c)4374
d)279,936
<pre>{{{highlight_green(matrix(4,4, "(a)", 2(3^3 + 4), "=", 62, "(b)", (2 * 3)^3 + 4, "=", 220, "(c)", 2*3^((3 + 4)), "=", "4,374", "(d)", (2 * 3)^((3 + 4)), "=", "279,936"))}}}
