Answer:
a) [tex]b^{3}[/tex]
b) [tex]x^{3}[/tex]
Step-by-step explanation:
a) Since it is division, you just subtract the powers from each other
[tex]b^{7} /b^{4} =b^{7-4} =b^{3}[/tex]
b) First add the powers on the top, then divide
[tex]\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}[/tex]
