Question

(x⁶ X x⁴) ÷ (x² X x³) : If x = (-3), then find the value.

Answer 1

x ki power 10÷ x ki power 6 if x = -3

x ki power 4 then -3 ki power 4

ans will be 81

Answer 2

Solution :

x = ( -3 ) ----( 1 )

Value of ( x^6 × x⁴ ) ÷ ( x² × x³ )

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

We know the Exponential laws:

1 ) a^m × a^n = a^m+n

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

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

= ( x^6+4 ) ÷ ( x^2+3 )

= x^10 ÷ x^5

= x^10-5

= x^5

= ( -3 )^5 [ from ( 1 ) ]

= - 3^5

= - 243
