Question

x 2 • x 5

answer quick

Answer 1

I do not understand what you're asking, but here are two choices:
x2 · x5 = x10
x² · x ⁵ = x⁷

Answer 2

Supposing x^2 • x^5 is what you're asking.

When multiply exponents, you must make sure the base for the exponent is the same. In this case, they're both the same. When multiplying exponents, you add the exponents. 

So, the answer is x^7.
