Question

please simplify this​

Answer 1

Step-by-step explanation:

3^(1/2) × 4^(1/3) × 5^(1/4)

=3^(6/12) × 4^(4/12) × 5^(3/12)

=(3^6×4^4×5^3)^(1/12)

=(23328000)^(1/12)

= 4.1114

= 4

Answer 2

Step-by-step explanation:

$\sqrt{3 \:} \times \sqrt[3]{4} \times \sqrt[4]{5}$

(3)1/2 × (4)1/3 × (5)1/4

taking LCM of powers,

(3)1/2×6/6 . (4) 1/3×4/4 . (5)1/4×3/3

$(3 {}^{6 } ) {}^{12} \times ( {4}^{4} ) {}^{12} \times ( {5}^{3} ) {}^{12}$

${279}^{12} \times {196}^{12} \times {125}^{12}$

hope this is useful
