Answer 1

$a)5x + 6x + 4 - 6 = \\ 11x - 2$

$b)13 {y}^{8} - 5 {y}^{8} + 2 {x}^{3} + 6 {x}^{3} = \\ 8 {y}^{8} + 8 {x}^{3}$

$c)25ab {}^{2} - 15ab {}^{2} = \\ 10ab {}^{2}$

$d)6 {x}^{2} \times 9 {x}^{7} = \\ 54 {x}^{2 + 7} \\ 54 {x}^{9}$

$e)2 {a}^{5} \times 8 {a }^{9} + 4 {b}^{6} - 3 {b}^{6} = \\ 16 {a}^{14} + 4 {b}^{6} - 3 {b}^{6} \\ 16a {}^{14} + {b}^{6}$

$f) \frac{56 {x}^{2} }{7x} =8x$

$g)(5x {}^{9} ) {}^{7} = \\ {5}^{7} \times ( {x}^{9} ) { }^{7} \\ 78125 {x}^{63}$
