Factories 54m3n + 81m4n2 b) 15x2y3z + 25x3y2z + 35x2y2z

Part a)

Given the expression

Apply exponent rule:    

    ∵

Rewrite 81 as 3 · 27

Rewrite 54 as 2 · 27

Factor out the common term:   27m³n

Therefore,

Part B)

Given the expression

Apply exponent rule:    

Rewrite as

Factor out common term 5y²x²z

Therefore,

answer: it's d

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
