The product of the indices is . Option A is correct

Given the indices expressed as:

This can be expressed as"

According to the law of indices;

Applying this rule will give;

Hence the product of the indices is

Step-by-step explanation:

Here we are multiplying one fifth root of a quantity by another 5th root of another quantity.

Changing from radical to fractional exponent form yields

(4x^2)^(1/5)*(4x^2)^(1/5).  Actually, this is identical to the square of (4x^2)^(1/5);

(4x^2)^(2/5).  This is equivalent to  4^(2/5)*(x^2)^(2/5), or

16^(1/5)*(x^4)^(1/5).  This is the 5th root of 16x^4, which is the 2nd answer choice.

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
