Answer:
here we work with factorials, so if we have a whole number N, then:
N! = N*(N-1)*.....*2*1
then, for the given expressions we have:
1) 6! = 6*5*4*3*2*1 = 720.
2) 3!*21 = (3*2*1)*21 = 216
3) and the last expression seems incomplete, i guess this is:
11! = 11*10*9*8*7*6*5*4*3*2*1 = 39,916,800
Answer:
16 × 10^11= 1.6e+12
8 × 10^5= 800000
Step-by-step explanation:
<span>the main formula is (a - b)² = a² -2ab + b²
</span><span>as for 49x^2 – 56x + 16, it is the same of (7x -4)²
so the </span>the factored form of 49x^2 – 56x + 16 = (7x -4)(7x -4)
Answer:
Hello There!!
Step-by-step explanation:
Combine like terms:
•5t+8t-12t
•5t+8t=13t
•13t-12t=1t
•1t=t
hope this helps,have a great day!!
