Question

1 Find the cube root of  125/625?

2 Evaluate 2-3+3-2

​

Answer 1

Answer:

1. 1/(³√5)

2.

3.

Step-by-step explanation:

1.

³√125/625

=³√(5)³/ (5)⁴

=5/5(³√5)

=1/(³√5)

2.

2-3+3-2

= 0

3.

16 books weigh = 9.6 kg

1 book weigh = (9.6 ÷ 16) kg

12 books weigh = {(9.6 × 12) / 16} kg

=6.12 kg
