could someone help me with math?

Question

Use the properties of exponents to simplfy this expression. You may leave your answer as a number to a power.

(-3k)^5

Answer 1

Inside the parentheses is a MONOMIAL: -3 multiplied by k (the 'unknown').  The exponent 5 applies to both the factor -3 and to k, so you get (-3)^5 = -243 times k^5  

 

Answer: -243k⁵
