Answer:
The CPI increased 3.42% in Month 2.
Step-by-step explanation:
In a spreadsheet, the weighted sum is easily computed using the SUMPRODUCT( ) function. It multiplies the corresponding values of two arrays, then returns the sum of those products. If one of the values is a weight, then the result is a weighted sum.
Your CPI is computed as the weighted sum of the prices of the individual products. The percentage change is computed in the usual way:
pct change = ((new value)/(old value) -1) × 100%
Of course, the spreadsheet can format a fraction as a percentage, so the computation of the change can stop after 1 is subtracted from the ratio.
Answer:
3x³y √(5xy)
Step-by-step explanation:
√(3x⁴y) √(15x³y²)
Multiply the radicands. When multiplying, add the exponents (xᵃ xᵇ = xᵃ⁺ᵇ).
√(45x⁴⁺³y¹⁺²)
√(45x⁷y³)
To simplify further, we need to factor out perfect squares (anything with an even exponent).
√(3²·5 x⁶x y²y)
√(3²x⁶y²) √(5xy)
Take the square root of the perfect square (halve the exponent).
3x³y √(5xy)
