Answer:
9.936
Step-by-step explanation:
In(x+5)*x=5
ln(x^2+5x)=5
e^5=x^2+5x
148.4131=x^2+5x
x^2+5x-148.4131=0
x is 9.936 because logs can't be negative
Answer:
They practiced a total of 75 math facts in all!
60 + 15 = 75 :D
. The number is either 10^1 or 10^3 or 10^ 5 or . . . .
<span>If it is more than 10, then it is not 10^1. The next possibility is 10^3which is 1000, which has factors 2, 5, 10, 20, 25, 40, 50, 80, . . . . . </span>
<span>What constitutes a "multiplication sentence" exactly ? This is not a standard mathematical term. Do you mean "reduce it to its prime factors" ? </span>
<span>1000 = 2 x 2 x 2 x 5 x 5 x 5 </span>
<span>which is a lot more than 4 factors. Or not, if you write it as 2³ x 5³. </span>
<span>But you could say the same about 100 000 = 2^5 x 5^5 </span>
<span>or about 10 000 000 = 2^7 x 5^7 </span>
<span>Take your pick. This is a very badly stated question. </span>
