Hi there!
[tex] {x}^{2} \times {x}^{5} = x {}^{2 + 5} = {x}^{7} [/tex]
We can also write is out entirely.
[tex] {x}^{2} = x \times x[/tex]
[tex] {x}^{5} = x \times x \times x \times x \times x[/tex]
[tex] {x}^{2} \times {x}^{5} = \\ (x \times x ) \times (x \times x \times x \times x \times x) = \\ x \times x \times x \times x \times x \times x \times x = \\ {x}^{7} [/tex]
