Im a bit stuck, Help!

Answer:
false
Step-by-step explanation:
cube root implies that the number equal to it, in this case 30, can be multiplied thrice and equal the cube root.
for example, √25 = 5, meaning that 5 x 5 = 25.
if this equation were true, 30 x 30 x 30 would equal 90. because it does not, this equation is false.
