\( \sqrt {{\rm{25}}{{\rm{x}}^{\rm{2}}}}\)
\(5 x\)
Explanation
\( \sqrt {{\rm{25}}{{\rm{x}}^{\rm{2}}}} = {\rm{ }}\sqrt {{{\left( {{\rm{5x}}} \right)}^2}} = {\rm{ 5x}}\)
\( \sqrt {81{x^2}}\)
If x = 3, then \(x^{x} (x) = \)
If a = 4 and b = -6, what is the value of the expression \(- {a^3} - {a^2}b + 7{b^2} - ab + 9?\)
If \(\frac{0.08}{\text{ x}} = 1\), then x =
Which of the following is not a synonym for \( {9^3}\)?
