PLEASE HELP URGENT‼️‼️ Tonia was simplifying the expression: (3x)2 . x4. She wrote 3x8 as the
simplest form.
——————————————
Part A) Simplify the problem correctly.
——————————————
Part B) Describe the error(s) that Tonya made.

Part A

(3x)^2*x^4

(3x)*(3x)*x^4 expand out (3x)^2

(3*3)*(x*x*x^4)

9x^6

 9x^6

Part B

It appears that Tonya forgot to square the 3 term and had this as her steps

(3x)^2*x^4

3x^2*x^4

3x^(2*4)

3x^8

Which is incorrect as the answer in part A indicates.

Not only is the '3' part wrong, but also the exponent of 8. Instead of multiplying the exponents, she should have added them.

The rule is a^b*a^c = a^(b+c). In this case, a = x, b = 2 and c = 4.

So x^2*x^4 = x^(2+4) = x^6

the correct answer is d

hope this
