Question

which expression equals 9^3 sqrt 10
A. 5 sqrt 10 + 4 sqrt 10
B. 5^3 sqrt 10 + 4 ^3 sqrt 10
C. 5 sqrt 10 + 4^3 sqrt 10
D. 5^3 sqrt 10 + 4 sqrt 10

Answer 1

Answer:

Option B is correct.

$5\sqrt[3]{10} + 4\sqrt[3]{10}$

Step-by-step explanation:

Given the equation:   $9\sqrt[3]{10}$

We can write 9 as:

9 = 5+ 4

then;

$(5+4)\sqrt[3]{10}$

Using distributive property:

$a\cdot(b+c)= a\cdot b+ a\cdot c$

Apply distributive property:

$5\sqrt[3]{10} + 4\sqrt[3]{10}$

Therefore, the expression which is equivalent to  $9\sqrt[3]{10}$ is $5\sqrt[3]{10} + 4\sqrt[3]{10}$
