Question

find the value of a​

Answer 1

5√5*5^3 ÷5^-3/2 = 5^a+2

5*5^1/2*5^3÷5^-3/2=5^a+2

5^1+1/2+3 ÷ 5^-3/2=5^a+2

【If bases are same powers should be added ex: x^2*x^3=x^5】

5^2+1+6/2÷5^-3/2=5^a+2

【 Do LCM】

5^9/2 ÷ 5^-3/2=5^a+2

5^9/2*5^3/2=5^a+2

【ex:1/x^-2=x^2】

5^9/2+3/2=5^a+2

5^12/3=5^a+2

5^4=5^a+2

4=a+2

a=4-2

=>a=2
