The expression (3x^7)^4 is equivalent to c^n what is the value of c
Nimfa-mama [501]

Answer:

n= 21

c= 3x

Step-by-step explanation:

The expression is given as;

(3x⁷)⁴

Apply the brackets law of indices which states that :

If a term with a power is itself raised to a power then the powers are multiplied together

(xᵃ)ᵇ = xᵃˣᵇ

Applying the same;

(3x⁷)⁴ = 3x²¹

If 3x²¹ = c^n

Then n = 21

and

c= 3x

A box is filled with 2 blue cards, 4 brown cards, and 6 yellow cards. A card is chosen at random from a box. What is the probabi
Finger [1]

Answer:

Therefore the probability that the card is not brown is \frac12.

Step-by-step explanation:

Probability: Probability is the ratio of the favorable outcome to the total outcome.

Probability =\frac{\textrm{Favorable outcome}}{\textrm {Total outcome}}

Given that, a box contains  2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.

Total number of cards= (2+4+6)=12

∴P(getting a brown card)

=\frac{\textrm{No. of brown card}}{\textrm{Total no. of card}}

=\frac{6}{12}

=\frac12

∴P(not getting a brown card)

=1 - P(getting a brown card)

=1-\frac12

=\frac12

Therefore the probability that the card is not brown is \frac12.
