Question

me ajudem com a raiz quadrada pfvr
​

Answer 1

a) ⁴√a = 3 --> a^(1/4) = 3

a^(4/4) = 3^4

a = 3^4

a = 81

b) ⁵√a = 2 --> a^(1/5) = 2

a^(5/5) = 2^5

a = 2^5

a = 32

c) ⁷√a = 1 --> a^(1/7) = 1

a^(7/7) = 1^7

a = 1

d) ⁿ√625 = 5 --> 625^(1/n) = 5

5^4^(1/n) = 5

5^(4/n) = 5¹

4/n = 1

n = 4

e) ⁿ√64 = 2 --> 64^(1/n) = 2

2^8^(1/n) = 2

5^(8/n) = 2¹

8/n = 1

n = 8
