Answer:
Below in bold.
Step-by-step explanation:
∛-12
The nearest cube to -12 is -8 ( -27 is the next after -12)
a) The answer is -2.
b) we can do this by trial and improvement
It must be between -2 and -3, closer to -2 than 3 so first we guess -2.1
(-2.1)^3 = -9.261
(-2.2)^3 = -10.648
(-2.3)^3 = `2.167 - very close
Answer is -2.3 .
