Answer : D

Cross multiply:
9n + 63 = 8n + 40

Subtract 63 from both sides:
9n + 63-63= 8n + 40-63

Simplify:
9n=8n-23

Subtract 8n from both sides:
9n-8n= 8n-23-8n

Simplify:
n=-23

Simplest form of (36^)1/3
nekit [7.7K]

3,301927249 = ³√36

As discussed in one of my videos on my channel [USERNAME: MATHEMATICS WIZARD] on the Six Rational Exponential Rules, this one states that with a numerator of 1 in the exponent, you take the multiplicative inverse [reciprocal] of the fraction, and set the whole number equal to the root, bringing your a inside the radical, which is 36.

ⁿ√aᵐ = aᵐ\ⁿ → works for both: numerator ≥ 1

I am joyous to assist you anytime.

Solve the system: 10x-9y=8 21y+15x=0.5
artcher [175]

Answer:

x = 1/2 y = -1/3

Step-by-step explanation:

Split it into 2 equations:

10x-9y=8

and

21y+15x=0.5

10x - 9y = 8

Step 1: Divide both sides by 10:

x = (8+9y)/(10)

Substitute x = (8+9y)/(10) into 21y+15x=0.5 :

21y + (3(8+9))/(2) = 0.5

Solve for y

<u>y= -1/3</u>

Substitute y= -1/3 into x = (8+9y)/(10)

<u>x = 1/2</u>

katrin2010 [14]

Answer:

\dfrac{225}{64}

Step-by-step explanation:

(4^3)^{-2} \times (2^3)^4 \times (\dfrac{8}{15})^{-2} =

= (2^2)^{-6} \times 2^{12} \times (\dfrac{15}{8})^{2}

= 2^{-12} \times 2^{12} \times \dfrac{225}{64}

= \dfrac{225}{64}
