Answer 1

Explanation:

1 × a = a

a² = a*a ; a³ = a*a*a .....

`((a)/(b)) ^(n) = (a^(n) )/(b^(n) )`

(1).

(a).
`7^(5)`

(b).
`((1)/(7)) ^(6)` =
`(1)/(7^(6) )`

(c).
`(9.3)^(9)`

(2).

(e).
`((1)/(2) )^(4) =(1)/(2^(4) )` =
`(1)/(2*2*2*2)` =
`(1)/(16)`

(f).
`((1)/(3) )^(2)` =
`(1)/(3)` ×
`(1)/(3)` =
`(1)/(9)`

(3).

x² = 30² + 16² = 900 + 256 = 1156 = 34² ⇒ x = 34 units
