Question

64a^3-b^3/343
pls Answer as soon as possible he submission tomorrow

Answer 1

Answer:

Step-by-step explanation:

We know that,

$a^{2} +b^{3 }= (a-b)(a^{2} +ab+b^{2} )$

∴$64a^{3} - \frac{b^{3} }{343}$ = $4^{3} . a^{3} - \frac{b^{3}}{7^{3} }$

∴$4^{3} - (\frac{b}{7})^3 = (4a - \frac{b}{7})(16a^{2} + \frac{4}{7}ab -\frac{b}{49}^2)$

Hope this helps...
