Answer 1

Answer:

a) $b^{3}$

b) $x^{3}$

Step-by-step explanation:

a) Since it is division, you just subtract the powers from each other

$b^{7} /b^{4} =b^{7-4} =b^{3}$

b) First add the powers on the top, then divide

$\frac{x^{1} *x^{5} }{x^{2} *x^{1} } =\frac{x^{1+5} }{x^{2+1} } =\frac{x^{6} }{x^{3} } =x^{6-3} =x^{3}$
