Answer 1

Step-by-step explanation:

(a) Value of {(625)^-½}² is -

(i) 1/625 ✔

(ii) -25

(iii) -625

(iv) 25

» {(25)^²×-½}²

» {(25)^-¹)}²

» (25)-²

» 1/(25)²

• » 1/625

(b) If 5^x = 1, value of x is -

(i) 5

(ii) 1/25

(iii) 0 ✔

(iv) 1/5

As we know that :-

• a^0 = 1

Then,

» 5^0 = 1

Hence,

The value of x is 0

(c) Value of {27^⅓ + 64^⅓}² is -

(i) 7^⅓

(ii) 49 ✔

(iii) 7^½

(iv) 1/7

» {3^³×⅓ + 4^³×⅓}²

» (3¹ + 4¹)²

» (7)²

• » 49
