Rewrite the expression in the form 5^n
(5^3)^2=?

Answers

This problem is all about bases and exponents.  Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

That's the simplification as long as you are "allowed" to leave the exponent as a negative number.

The answer is 5^6 because if we have an exponent to the power of exponent we have to multiply the powers..

Which function is nonlinear?

Answers

Answer:

Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Nonlinear functions are all other functions. An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.
