Question 373644
{{{(3x^10y^9)^3}}}
For this problem we will be using the rule for exponents: {{{(a*b)^q = a^q*b^q}}}. Before we start however, a couple of comments:<ul><li>If you have trouble remembering the rules for exponents or if you have trouble figuring out which rule for exponent to use, write the expression without exponents and simplify it this way.</li><li>The property mentioned above can easily be misused. It is critical to understand that this property <b>only</b> applies when the expression in the parentheses is just a single term. It does not apply to an expression that has more than one term. For example, the rule does not apply to {{{(a+b)^q}}}</li></ul>
Using the property on your expression we get:
{{{(3)^3*(x^10)^3*(y^9)^3}}}
{{{3^3 = 27}}}. For the rest we will use another rule for exponents: {{{(a^p)^q = a^(p*q)}}}:
{{{27*x^(10*3)*y^(9*3)}}}
which simplifies to:
{{{27*x^30*y^27}}}
