Question

Find the value of P if
(i) (2/5 )3 x (2/5)6 = (2/5)2p+1

Answer 1

Answer:

p= 47/20 or 2 7/20

Step-by-step explanation:

2/5 × 3= 6/5

2/5 × 6= 12/5

6/5 × 12/5= 72/25

72/25= (2/5)2p+1

72/25= 2/5 × 2p+1

72/25= 4/5p +1

Move +1 to the other side becomes -1

72/25 -1 = 4/5p

47/25 = 4/5p

47/25 × 5/4 = p

235/100= p

Simplify

47/20 or 2 7/20=p
