Answer 1

x^( 2a - b ) + ( 2b + c ) + ( 2c + a ) =

x^2a + a + 2b - b + 2c + c =

x^3a - b + 3c

Answer 2

Step-by-step explanation:

Simply add the exponents after combining the bases

${x}^{2a - b} \times {x}^{2b - c} \times {x}^{2c + a}$

$= {x}^{2a - b + 2b - c + 2c + a}$

$= {x}^{3a + b + 3c}$
