X^2-14+5 I’m not sure though
The median is the number in the middle setting the data up from least to greatest.
2, 3, 4, 4, 9, 10, 11, 11, 12, 15.
Median = 9.5
The mean is all the numbers added up and divided by how many there are.
2+ 3 + 4 + 4 + 9 + 10 + 11 + 11 + 12 + 15/10
Mean = 8.1
I'm not sure about the other two.
Answer:
1. (3x²y³z)²=9x⁴y⁶z²
2. (2m³n⁻⁴)³=8m⁹n⁻¹²
Step-by-step explanation:
Both questions require knowledge of two rules of indices/powers:
(xy)ᵃ=xᵃyᵃ (when numbers multiplied by each other are put to a power, that is equal to the product of each number to that power)
(xᵃ)ᵇ=xᵃᵇ (when a number to a power is put to another power, that is equal to the number to the power of the product of the powers)
1.
(3x²y³z)²
=(3²)(x²)²(y³)²(z²)
=(9)(x²⁽²⁾)(y³⁽²⁾)(z²)
=9x⁴y⁶z²
2.
(2m³n⁻⁴)³
=(2³)(m³)³(n⁻⁴)³
=(8)(m³⁽³⁾)(n⁻⁴⁽³⁾)
=8m⁹n⁻¹²
Hope this helps! :D
