x^( 2a - b ) + ( 2b + c ) + ( 2c + a ) =
x^2a + a + 2b - b + 2c + c =
x^3a - b + 3c
Step-by-step explanation:
Simply add the exponents after combining the bases
[tex] {x}^{2a - b} \times {x}^{2b - c} \times {x}^{2c + a} [/tex]
[tex] = {x}^{2a - b + 2b - c + 2c + a} [/tex]
[tex] = {x}^{3a + b + 3c} [/tex]
