If a=-4xa=−4x and b=5ib=5i, then find the value of ab^2ab 2 in fully simplified form.

Sagot :

The value of ab^2 in simplified form is -1

Given the following expressions:

  • a = 4x
  • b = 5i

We are to evaluate the expression [tex]ab^2[/tex]

Substitute the given parameters into the formula to have:

[tex]ab^2 =4x(5i)^2\\ab^2 = 4x(25i^2)\\ab^2=4x(50(-1))\\ab^2=-100x[/tex]

Hence the value of ab^2 in simplified form is -100x
