Question

gys plz tell these three answers correctly​

Answer 1

Step-by-step explanation:

(I) (-8)ⁿ = 4096

(-8)ⁿ= (-8)⁴

SINCE THE BASES ARE SAME , POWERS CAN BE COMPARED :-

∴ n = 4

(II) [12² + 6⁻² + 7⁰÷ ( 5²+5)]

⇒[ 144 + $\frac{1}{36}$+ ( 1 ÷ 30)]

⇒[144 +  $\frac{1}{36}$ + $\frac{1}{30}$]

⇒144 +$\frac{11}{180}$ [ Simplify it further]

(III)16⁸ ÷ 8⁴

⇒2³² ÷ 2¹²

⇒2²⁰

HOPE IT HELPS YOU :)
