Answer:
The answer to your question is the second option
Step-by-step explanation:
Expression
Process
1.- Divide the fraction in numerator and denominator
a) Numerator
[(x²y³)⁻²]³ = (x⁻⁴y⁻⁶)³ = x⁻¹²y⁻¹⁸
b) Denominator
[(x⁶y³z)²]²= (x¹²y⁶z²)³ = x³⁶y¹⁸z⁶
2.- Simplify like terms
a) x⁻¹²x⁻³⁶ = x⁻⁴⁸
b) y⁻¹⁸y⁻¹⁸= y⁻³⁶
c) z⁻⁶
3.- Write the fraction
Answer:
Agreed
Step-by-step explanation:
Answer:
150x÷×÷320y
Step-by-step explanation:
it's hard to tell in writing I can speak it but
The answer is $2.25
I would use this proportion
24 / 3 18/x
18 times 3=54
54 divided by 24=2.25
X=$2.25
