artcher [175]

Answer:

D)  250

Step-by-step explanation:

A) 552

552 ÷ 2 = 276

552 ÷ 5 = 110.4      

     

B) 255

255 ÷ 2 = 127.5

255 ÷ 5 = 51            

C) 525

525 ÷ 2 = 262.5

525 ÷ 5 = 105

D) 250

250 ÷ 2 = 125              

250 ÷ 5 = 50

D is the only answer where both 2 and 5 divide evenly, so it is your answer.

What is 8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³ in standar form?
vovangra [49]

The expression in standard form is n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶

<h3>How to express in standard form?</h3>

The expression is given as:

8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³

Collect the like terms

8mn⁵ -mn⁵ - 2m⁶ -4m⁶ + 5m²n⁴ +9m²n⁴+n⁶ - 4m³n³ - m³n³

Evaluate the like terms

7mn⁵ - 6m⁶ + 14m²n⁴+n⁶ - 5m³n³

Rewrite in standard form

n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶

Hence, the expression in standard form is n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶
