Question

If x = 2, then find the value of x⁸÷x²*x²

Answer 1

x^8÷x²×x²
x^8-2*x²
x^6*x²
x^6+2
x^4
so,
x=2
2^4
2×2×2×2
====16...

Answer 2

Solution :

****************************************

We know the Exponential laws:

i ) a^m/a^n = a^m-n

ii ) a^m × a^n = a^m+n

*****************************************

Here ,

x^8 ÷ x² × x²

= (x^8 - 2) × x²

= x^6 × x²

= x^6+2

= x^8

= 2^8 [ Given x = 2 ]

= 256
