Question

a⁴=64 what is the answer

Answer 1

a^4 = 2^6

a = 2^6/4

a = 2^3/2

a = 2*sqrt2

Answer 2

Solution ;-

$as \: per \: given \\ = > {a}^{4} = 64 \\ = > a = \sqrt[4]{64} \\ = > a = {64}^{ \frac{1}{4} } \\ = > a = 2 {}^{6 \times \frac{1}{4 } } \\ = > a = {2}^{ \frac{{\cancel{6}}}{{\cancel{4}}} } \\ = > a = 2 {}^{ \frac{3}{2} } \\ = > a = \sqrt{2 {}^{3} } \\ = > a = \sqrt{8} \\ = > a = 2 \sqrt{2}$
