Question

Answer 10th and 19th

Answer 1

Answer:

10)$\sqrt{248 + \sqrt{52 + \sqrt{144} } }$

=

$\sqrt{248 + \sqrt{52 + 12} }$

=

$\sqrt{248 + \sqrt{64} }$

=

$\sqrt{248 + 8}$

=

$\sqrt{256}$

=16

19)Volume of cube: 5832 m3

Volume= each side cube

Each side of cube: cbrt(5,832) m3

=18 m

Answer 2

10) √248+ √(52 +√144))

= √248 + √(52 +12))

= √(248 + √(64))

= √(248+8)

= √256

= 16

19)volume of cube = 5832

a^3 = 5832

5832 = 3^6. 2^3

a= 3^2 × 2 = 18

side = 18
