if a=4, b=-2, c=3

Question

simplify
4c square*3c4/c3

(b)2(3x+1)-(x+2)

Answer 1

not sure of your notation.
try using ^ for exponents, as in

x^2 or y^3
If you want a root, try using the special characters √ ∛ ∜

or use fractional exponents:
x^1/2 for square root, etc.

or, use a recognizable function name such as

sqrt(x) cuberoot(x) 4throot(x) etc.

(b) 2(3x+1)-(x+2)
= 6x + 2 - x - 2
= 5x
