Question

simplify (1³+2³+3³) ½​

Answer 1

Step-by-step explanation:

=(1³+2³+3³)1/2

=(1×1×1+2×2×2+3×3×3)1/2

=(1+8+27)1/2

=36×1/2

=18.

This is the right answer.

Answer 2

༒ Required Solution -

$(1^{3} + {2}^{3} + {3}^{3}) \frac{1}{2}$

$= (1 \times 1 \times 1) + (2 \times 2 \times 2) + 3 \times (3 \times 3 \times 3) \frac{1}{2}$

$= (1 + 8 + 27) \frac{1}{2}$

$= 36 \frac{1}{2}$

$= ( {2}^{2} \times {3}^{2} ) \frac{1}{2}$

$= ( {2}^{2} \times \frac{1}{2} ) \times ({3}^{2} \times \frac{1}{2} )$

$= 2 \times 3$

$= 6$
