Which international organization recently partnered with

6² + 4³ + 625^(1/4) - ? = 10²

Find the value of the given expression.

[76 – {90 ÷ 5 × (24 – 36 ÷ 3) ÷ 3}]

72% of 486 – 64% of 261 = ?

30 of 20 - 40 + 182 - 23 × ? = 8³ 

What are the values of k, if the roots of the equation x² + 2(k - 4)x + 2k = 0 are equal?

3.55 + 1.05 + 2.5 × 13 – 12% of 12.5 = ?

What will come in the place of question mark (?) in the given expression?

(144 × 16 ÷ 12) × 6 = ? 

[∛(3375/19683  )- ∛(125/1728  )  ] ÷ ∛(64/729)  = ? - 3/8 

√(24²+285-8²-172) = ?²

8⁹ ÷ 512 × (1/64) = (2³)^?
