Step-by-step explanation:

Given

:

Required

Find equivalent expressions

To solve this question; we'll simplify options a to do, one after the other

a:

From laws of indices;

This implies that;

From laws of indices;

This implies that

Hence,   is equivalent to

b.

From laws of indices;

This implies that

From laws of indices;

This implies that

Hence; is not equivalent to

c.  

From laws of indices;

This implies that

Hence, is equivalent to

d.  

From laws of indices;

This implies that

From laws of indices;

This implies that

Hence, is equivalent to

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
