Answer 2

the product x3⋅x4. Both terms have the same base, x, but they are raised to different exponents. Expand each expression, and then rewrite the resulting expression. ... Write each of the following products with a single base. Do not simplify further. ... notation. a 3.547×1014; b −2×106; c 7.91×10−7; d −8.05×10−12 ..
