Simplify each expression. use positive exponents.

1)  the first step to solving this is to know that any non zero expression that is raised to the power of zero will equal 1.
m³ x 1
any expression multiplied by 1 remains the same
m³ 
now express this with a positive exponent using  = 
m³ x 
now calculate the product

this means that the correct answer to number one is 
2) the first step for solving this expression is to reduce the fraction with a

now reduce the fraction with 

this means that the correct answer to question 2 is
3) the first step to solving this expression is to express with a positive exponent using tex] a^{-n} [/tex] = 
( ×  × x³ ) 
now calculate the product
(
now express with a positive exponent using () = ()
()
to raise a fraction to a power,, you need to raise the numerator and denominator to that power.

this means that the correct answer to question 3 is
let me know if you have any further questions

It’s going to be d. 4x^2-4x-19’
