The length and width of the television could be any two numbers whose product is 70.
You can first take out an x^2 from each number , 3x^6 - 39x^4 + 108x^2 = x^2 ( 3x^4 - 39x^2 + 108) Then just factor and solve for the zero's of the equation
Answer:
To avoid expansion, you can just use the power of a power rule and multiply the two exponents from the start.
Step-by-step explanation:
(<em>x</em>^4)^3
= <em>x</em>^4×3
= <em>x</em>^12
X^1/2 ( x + 3) (x - 6)
= x^1/2 ( x^2 - 3x - 18)
= x^5/2 - 3x^3/2 - 18x^1/2
= (sqrt x)^5 - 3 (sqrt x)^3 - 18x^1/2
