Question

4x^3(6x^2 - 1)
24x5 - 1
24x5 - 4x3
24x6 - 1
24x6 - 4x3

Answer 1

Simplify this expression.

Answer 2

Out of the options, the answer is B. 24x^5 - 4x^3, why?
Because 4x^3 multiplies against everything in parenthesis, this instantly cancels out options A and C because 1 would no longer be there. Now as for the final two, with the only differences being '^5' and '^6', we know it's '^5' because when multiplying exponents together it becomes addition and when dividing exponents it becomes subtraction, so...
3 + 2 = 5, therefore giving you 24x^5 - 4x^3.
I hope that helps in someway! Have a great day! ;)
