Question

What is the value of x^3\cdot y^1x ​3 ​​ ⋅y ​1 ​​ x, start superscript, 3, end superscript, dot, y, start superscript, 1, end superscript when x=5x=5x, equals, 5 and y=10y=10y, equals, 10?

Answer 1

The expression $x^3y$ means that you have to cube the value of $x$ and multiply it by the value of $y$.

So, the value of $x$ is 5, which becomes 125 when cubed. When we multiply it by the value of $y$, which is 10, the result is 1250:

$x^3y = 5^3\cdot 10 = 125\cdot 10 = 1250$
