Answer:a)m=6
b)m=9
c)m=50
Step-by-step explanation:
NB:all the three questions have the same base so in our case we will ignore them and use only the powers.
1)in 2^m/2^-2=2^3
ignore the bases which is 2
the 2^-2 its power will be 1/2 because its a negative power
a)m/1/2=3 so divide both sides by the recipricol of 1/2 to get
m=6
b)ignore the bases again which are 3
m*6/1/3=18
you will first get rid of 1/3 by dividing both sides by its reciprical to be left with only 6m
you then divide again both sides by 6 so we can get the value of m which is
m=9
c)ignore the bases which is 6
m*3*1/2/1/5=12
3/2m/1/5=15
divide both sides by the reciprical of 1/5 to be left with only 3/2m
divide again both sides by the reciprical of 3/2 to get the value of m which is
m=50
NB:recipricals apply to only fractions and the bases with negative powers will form fractions
