If 5√5 x 5^3 + 5^-3/2 = 5 ^(a + 2), then the value of a is:
Read Solution (Total 2)
-
- 5^1x5^1/2x5^3+5^-3/2 = 5^(a+2)
5^3/2x5^3+5^-3/2
5^9/2+5^-3/2
5^6/2
5^3 = 5^(a+2)
now, 3 = a+2

- a=2.5
Explanation :
5√5 x 5^3 + 5^-3/2 = 5 ^(a + 2)
11.18 x 125 + 111.18 = 5^a 5^2
1397.5=5^a (25)
1397.5/25=5^a
55.9=5^a
therefore a=2.5 i.e 5^2.5=55.9
