v^-7 x v^7

its saying to write as a positive exponent only?

sorry - can't be done

v^-7 * v^7 = v^(-7+7) = v^0 = 1

ok thanks anyways

x^5/8x^3

To simplify the expression v^-7 x v^7 and write it with a positive exponent only, we can use the product of powers rule.

The product of powers rule states that when you multiply expressions with the same base, you add the exponents.

In this case, we have v^-7 and v^7 as the bases are the same (v). The exponents are -7 and 7.

Therefore, v^-7 x v^7 can be simplified as v^(-7+7) = v^0.

Any non-zero number raised to the power of 0 is equal to 1. So, v^0 = 1.

Therefore, the expression v^-7 x v^7 can be written as 1 with a positive exponent only.
