Mario tried to solve an equation step by step.

Mathematics
1 answer:
Zarrin [17]3 years ago
5 0

Answer:

Step 2

Step-by-step explanation:

Mario made a mistake in Step 2 when substracting \frac{1}{3} from \frac{4}{3}. When substracting his result ended up being \frac{2}{3} but it is actually....

\frac{4}{3} - \frac{1}{3} = \frac{4-1}{3} = \frac{3}{3} = 1

so the right answer is q = 1

How do you solve the equation 7^(7n+7)=2,401
RoseWind [281]
7^(7n + 7) = 2401
apply log on both sides to solve the equation
log 7^(7n + 7) = log 2401
the power is brought forward
(7n + 7) log 7 = log 2401
7n +7 = log 2401 / log 7
7n + 7 = 4
7n = -3
n = -3/7

Hope it helped!

The expression (y-20)(y5)3 is equivalent to ya. What is the value of a?
Leno4ka [110]

Answer:

y¹⁵-20y¹⁴

Step-by-step explanation:

I'm going to assume that your problem looks like this

(y-20)(y^5)^3

(x^n)^y=x^{n*y}

which means we have

(y-20)*y^{15}\\\\y^{16}-20y^{15}=ya\\\\*y^{15}-20y^{14}=a
