Question

if 5¹⁰×5‐²÷5²+a = 125find the value of a ,a is also power of 5²​

Answer 1

Step-by-step explanation:

Given,

5^10×5^-2÷5^2+a=125

5^10×1/5^2×1/5^2+a=125

5^10×1/5^4+a=125

5^6+a=125

a=125-15,625

a= -15,500

Now, given that a is the power of 5^2

so, a= -15,500×1/5^2

a= -620

-620 is the answer or the value of a
