Simplify the given expression.

125 ÷ 5 ÷ 5 × 5

If 3ˣ × 9¹⁵ × 27⁶ = 81¹⁶, then the value of x is:

Value of$$\frac{0.97 \times 0.97 \times 0.97 + 0.03 \times 0.03 \times 0.03}{0.97 \times 1.94 - 1.94 \times 0.03 + 0.03 \times 0.06}$$​ is equal to:

The value of $$\frac{(0.\overline{29} \div 0.\overline{32}) \times 6.6}{0.\overline{95} \div 1.\overline{05} \times 1.\overline{2}}$$​ is

Simplify the following.
$$3\left(\left(\frac{7}{3}\right)x^{2} - 25x + 12\right) - 7\left(x^{2} + 8x - 16\right)$$​
