Question

factorise
${a}^{3} - 2 \sqrt{2} {b}^{3}$
please answer ​

Answer 1

Answer:

a^3 -2 \sqrt{2} {b}

Step-by-step explanation:

Basically, the root of a product is equal to the product of the roots of each factor

a^3 -2 \sqrt{b^2} {2} => then Reduce the index of the radical and exponent with 2

a^3 -2b \sqrt{2} => for this last part, you must use the commutative property to reorder the terms

Answer> a^3 -2 \sqrt{2} {b}
